Some msm targets have timers whose lower bits are unreliable. So, we
present our timers as lower frequency than they actually are, and ignore
the bottom 5 bits on such targets. This compensation was erroneously
removed from the msm_read_timer_count function, so restore it.
This was broken by 94790ec25 "msm: timer: SMP timer support for msm".

When runtime PM is disabled, device clocks need to be enabled on
device add and disabled on device remove. This currently is not
happening because in the !PM_RUNTIME case, no notifiers are registered
for OMAP1 devices.
Fix this by ensuring notifiers are registered, even in the !PM_RUNTIME case.

This patch updates the board specific USB support
code for the sh7372 Mackerel board.
With this patch applied port CN22 is driven by the
recently added renesas_usbhs driver using the first
USB controller included in sh7372 aka USBHS0.
Hotplugging of USBHS0 unfortunately has to be
handled by software polling. The sh7372 SoC itself
obviously supports hotplug notification by IRQ but
on the Mackerel board this IRQ happens to be used
for the touch screen.
Also fix the pinmux configuration to avoid setting
up unused pins and fix minor spelling errors.

If the DT physical address is zero, this is equivalent to no DT.
Especially when the actual RAM physical address is not located at zero,

Will Deacon reports that:
In 52af9c6c ("ARM: 6943/1: mm: use TTBR1 instead of reserved context ID")
I updated the ASID rollover code to use only the kernel page tables
whilst updating the ASID.
Unfortunately, the code to restore the user page tables was part of a
later patch which isn't yet in mainline, so this leaves the code
quite broken.
We're also in the process of eliminating __ARCH_WANT_INTERRUPTS_ON_CTXSW
from ARM, so lets revert these until we can properly sort out what we're
doing with the context switching.
