pnv_pec_stk_pci_xscom_write() is pnv_pec_stk_pci_xscom_ops write
callback. It writes values into regs in the stack->nest_regs[] array.
The pnv_pec_stk_pci_xscom_read read callback, on the other hand, returns
values of the stack->pci_regs[]. In fact, at this moment, the only use
of stack->pci_regs[] is in pnv_pec_stk_pci_xscom_read(). There's no code
that is written anything in stack->pci_regs[], which is suspicious.
Considering that stack->nest_regs[] is widely used by the nested
MemoryOps pnv_pec_stk_nest_xscom_ops, in both read and write callbacks,
the conclusion is that we're writing the wrong array in
pnv_pec_stk_pci_xscom_write(). This function should write stack->pci_regs[]
instead.

This patch introduces pnv-phb4 user creatable devices that are created
in a similar manner as pnv-phb3 devices, allowing the user to interact
with the PHBs directly instead of creating PCI Express Controllers that
will create a certain amount of PHBs per controller index.
We accomplish this by doing the following:
- add a pnv_phb4_get_stack() helper to retrieve which stack an user
created phb4 would occupy;
- when dealing with an user created pnv-phb4 (detected by checking if
phb->stack is NULL at the start of phb4_realize()), retrieve its stack
and initialize its properties as done in stk_realize();
- use 'defaults_enabled()' in stk_realize() to avoid creating and
initializing a 'stack->phb' qdev that might be overwritten by an user
created pnv-phb4 device. This process is wrapped into a new helper
called pnv_pec_stk_default_phb_realize().

At this moment, stack->phb is the plain PnvPHB4 device itself instead of
a pointer to the device. This will present a problem when adding user
creatable devices because we can't deal with this struct and the
realize() callback from the user creatable device.
We can't get rid of this attribute, similar to what we did when enabling
pnv-phb3 user creatable devices, because pnv_phb4_update_regions() needs
to access stack->phb to do its job. This function is called twice in
pnv_pec_stk_update_map(), which is one of the nested xscom write
callbacks (via pnv_pec_stk_nest_xscom_write()). In fact,
pnv_pec_stk_update_map() code comment is explicit about how the order of
the unmap/map operations relates with the PHB subregions.
All of this indicates that this code is tied together in a way that we
either go on a crusade, featuring lots of refactories and redesign and
considerable pain, to decouple stack and phb mapping, or we allow stack
update_map operations to access the associated PHB as it is today even
after introducing pnv-phb4 user devices.
This patch chooses the latter. Instead of getting rid of stack->phb,
turn it into a PHB pointer. This will allow us to assign an user created
PHB to an existing stack later. In this process,
pnv_pec_stk_instance_init() is removed because stack->phb is being
initialized in stk_realize() instead.

The 'stack->phb_regs_mr' PHB4 passthrough XSCOM initialization relies on
'stack->phb' being not NULL. Moving 'stack->phb_regs_mr' region_init()
and add_subregion() to phb4_realize() time is a natural thing to do
since it's strictly PHB related.
The remaining XSCOM initialization is also related to 'stack->phb' but
in a different manner. For instance, 'stack->nest_regs_mr'
MemoryRegionOps, 'pnv_pec_stk_nest_xscom_ops', uses
pnv_pec_stk_nest_xscom_write() as a write callback. When trying to write
the PEC_NEST_STK_BAR_EN reg, pnv_pec_stk_update_map() is called. Inside
this function, pnv_phb4_update_regions() is called twice. This function
uses 'stack->phb' to manipulate memory regions of the phb.
This is not a problem now but, when enabling user creatable phb4s, a
stack that doesn't have an associated phb (i.e. stack->phb = NULL) it
will cause a SIGINT during boot in pnv_phb4_update_regions().
All this can be avoided if all XSCOM realize is moved to phb4_realize(),
when we have certainty about the existence of 'stack->phb'. A lot of
code was moved from pnv_phb4_pec.c to pnv_phb4.c due to static constant
and variables being used but the cleaner logic is worth the trouble.

Relying on stack->phb to write the xscom DT of the PEC is something that
we won't be able to do with user creatable pnv-phb4 devices.
Hopefully, this can be done by using pnv_phb4_pec_get_phb_id(), which is
already used by pnv_pec_realize() to set the phb-id of the stack. Use
the same idea in pnv_pec_dt_xscom() to write ibm,phb-index without the
need to accessing stack->phb, since stack->phb is not granted to be !=
NULL when user creatable phbs are introduced.

Similar to what was happening with pnv-phb3 buses,
TYPE_PNV_PHB4_ROOT_BUS set to "pnv-phb4-root-bus" is a bit too long for
a default root bus name. The usual default name for theses buses in QEMU
are 'pcie', but we want to make a distinction between pnv-phb4 buses and
other PCIE buses, at least as far as default name goes, because not all
PCIE devices are attachable to a pnv-phb4 root-bus type.
Changing the default to 'pnv-phb4-root' allow us to have a shorter name
while making this bus distinct, and the user can always set its own bus
naming via the "id" attribute anyway.

The TYPE_PNV_PHB3_ROOT_BUS name is used as the default bus name when
the dev has no 'id'. However, pnv-phb3-root-bus is a bit too long to be
used as a bus name.
Most common QEMU buses and PCI controllers are named based on their bus
type (e.g. pSeries spapr-pci-host-bridge is called 'pci'). The most
common name for a PCIE bus controller in QEMU is 'pcie'. Naming it
'pcie' would break the documented use of the pnv-phb3 device, since
'pcie.0' would now refer to the root bus instead of the first root port.
There's nothing particularly wrong with the 'root-bus' name used before,
aside from the fact that 'root-bus' is being used for pnv-phb3 and
pnv-phb4 created buses, which is not quite correct since these buses
aren't implemented the same way in QEMU - you can't plug a
pnv-phb4-root-port into a pnv-phb3 root bus, for example.
This patch renames it as 'pnv-phb3-root', which is a compromise between
the existing and the previously used name. Creating 3 phbs without ID
will result in an "info qtree" output similar to this:
bus: main-system-bus
type System
dev: pnv-phb3, id ""
index = 2 (0x2)
chip-id = 0 (0x0)

When creating a pnv_phb3_root_port using the command line, the first
root port is created successfully, but the second fails with the
following error:
qemu-system-ppc64: -device pnv-phb3-root-port,bus=phb3-root.0,id=pcie.3:
Can't add chassis slot, error -16
This error comes from the realize() function of its parent type,
rp_realize() from TYPE_PCIE_ROOT_PORT. pcie_chassis_add_slot() fails
with -EBUSY if there's an existing PCIESlot that has the same
chassis/slot value, regardless of being in a different bus.
One way to prevent this error is simply set chassis and slot values in
the command line. However, since phb3 root buses only supports a single
root port, we can just get an unique chassis/slot value by checking
which root bus the pnv_phb3_root_port is going to be attached, get the
equivalent phb3 device and use its chip-id and index values, which are
guaranteed to be unique.

Mypy 0.930, released Dec 22, changes the way argparse objects are
considered. Crafting a definition that works under Python 3.6 and an
older mypy alongside newer versions simultaneously is ... difficult,
so... eh. Stub it out with an 'Any' definition to get the CI moving
again.
Oh well.

0.920 (Released 2021-12-15) is not entirely happy with the
way that I was defining _FutureT:
qemu/aqmp/protocol.py:601: error: Item "object" of the upper bound
"Optional[Future[Any]]" of type variable "_FutureT" has no attribute
"done"
Update it with something a little mechanically simpler that works better
across a wider array of mypy versions.

pylint's dependency astroid appears to have bugs in 2.9.1 and 2.9.2 (Dec
31 and Jan 3) that appear to erroneously expect the qemu namespace to
have an __init__.py file. astroid 2.9.3 (Jan 9) avoids that problem, but
appears to not understand a relative import within a namespace package.
Update the relative import - it was worth changing anyway, because these
packages will eventually be packaged and distributed separately.
