FreeBSD does not understand #interrupt-map in a device tree. This prevents the
GIC from being set up correctly. This patch removes the #interrupt-map in the
device trees for the Base and Foundation FVPs. This enables correct boot of
FreeBSD on these platforms.
These changes have been tested with FreeBSD and an Ubuntu cloud image
(ubuntu-16.04-server-cloudimg-arm64-uefi1.img) to ensure compatibility with
Linux.

The `fvp-base-gicv3-psci` and `fvp-foundation-gicv3-psci` device tree source
files did not have psci node entries for `system off` and `system reset`.
Also the DTS files included `rtsm_ve-motherboard-no_psci.dtsi` instead of
`rtsm_ve-motherboard.dtsi`. As a result, the Linux kernel failed to invoke
the PSCI_SYSTEM_OFF/RESET API when being shutdown/reset. This patch corrects
this problem and also updates the corresponding DTB files.
This patch also removes `rtsm_ve-motherboard-no_psci.dtsi` and
`fvp-foundation-motherboard-no_psci.dtsi` files as they are no longer used.

From version 4.0 onwards, the ARM64 Linux kernel expects the device
tree to indicate the cache hierarchy. Failing to provide this
information results in the following warning message to be printed by
the kernel:
`Unable to detect cache hierarchy from DT for CPU x`
All the FVP device trees provided in the TF source tree have been
modified to add this information.

Device tree idle state bindings changed in kernel v3.18. This patch
updates the FVP DT files to use PSCI suspend as idle state.
The patch also updates the 'compatible' property in the PSCI node
and the 'entry-method' property in the idle-states node in the FVP
Foundation GICv2-legacy device tree.

This patch:
* Bumps the PSCI VERSION to 1.0. This means that
the PSCI_VERSION API will now return the value 0x00010000
to indicate the version as 1.0. The firmware remains
compatible with PSCI v0.2 clients.
* The firmware design guide is updated to document the
APIs supported by the Trusted Firmware generic code.
* The FVP Device Tree Sources (dts) and Blobs(dtb) are also
updated to add "psci-1.0" and "psci-0.2" to the list of
compatible PSCI versions.

This patch updates the representation of idle tables and cpu/cluster topology in
the device tree source files for the FVP to what the latest cpuidle driver in
Linux expects. The device tree binaries have also been updated.

TZC-400 is configured to set the last 16MB of DRAM1 as secure memory and
the rest of DRAM as non-secure. Non-secure software must not attempt to
access the 16MB secure area.
Device tree files (sources and binaries) have been updated to match this
configuration, removing that memory from the Linux physical memory map.
To use UEFI and Linux with this patch, the latest version of UEFI and
the updated device tree files are required. Check the user guide in the
documentation for more details.
Replaced magic numbers with #define for memory region definition in the
platform security initialization function.

- Use the TrustZone controller on Base FVP to program DRAM access
permissions. By default no access to DRAM is allowed if
'secure memory' is enabled on the Base FVP.
- The Foundation FVP does not have a TrustZone controller but instead
has fixed access permissions.
- Update FDTs for Linux to use timers at the correct security level.
- Starting the FVPs with 'secure memory' disabled is also supported.
Limitations:
Virtio currently uses a reserved NSAID. This will be corrected in
future FVP releases.

- The Foundation FVP is a cut down version of the Base FVP and as
such lacks some components.
- Three FDTs are provided.
fvp-foundation-gicv2legacy-psci:
Use this when setting the Foundation FVP to use GICv2. In this
mode the GIC is located at the VE location, as described in the
VE platform memory map.
fvp-foundation-gicv3-psci :
Use this when setting the Foundation FVP to use GICv3. In this
mode the GIC is located at the Base location, as described in the
Base platform memory map.
fvp-foundation-gicv2-psci :
Use this when setting the Foundation FVP to use GICv3, but Linux
is expected to use GICv2 emulation mode. In this mode the GIC is
located at the Base location, but the GICv3 is used in GICv2
emulation mode.
