ARM: shmobile: Insert align directives before 4 bytes data
In thumb2 mode instructions are not align to 4 byte. This patch insert
align directives before putting 4 byte data.

ARM: shmobile: Rework sh7372 sleep code to use virt_to_phys()
Instead of having a hard coded virt-to-phys address
conversion code in sleep-sh7372.S, rework the code
to do the conversion in C using virt_to_phys().
This removes the need for PLAT_PHYS_OFFSET which
in turn is needed for ARCH_MULTIPLATFORM.

ARM: sh7372: fix cache clean / invalidate order
According to the Cortex A8 TRM the L2 cache should be first cleaned and
then disabled. Fix the swapped order on sh7372.

PM / shmobile: Add support for the sh7372 A4S power domain / sleep mode
The sh7372 contains a power domain named A4S which in turn
contains power domains for both I/O Devices and CPU cores.
At this point only System wide Suspend-to-RAM is supported,
but the the hardware can also support CPUIdle. With more
efforts in the future CPUIdle can work with bot A4S and A3SM.
Tested on the sh7372 Mackerel board.
[rjw: Rebased on top of the current linux-pm tree.]

ARM: mach-shmobile: sh7372 A3SM support
This patch adds sh7372 A3SM power domain support.
The sh7372 A3SM hardware power domain contains the
ARM Cortex-A8 CPU Core including L2 cache. This
sleep mode can be seen as a one step deeper sleep
mode from the already existing Core Standby mode.
To wake up from A3SM sleep only a few wakeup sources
are supported - so the regular INTC controller will
not be able to help us unfortunately.
The code in this patch will enter A3SM sleep via the
regular Suspend-to-RAM interface in the case of only
wakeups supported by A3SM are enabled. If unsupported
wakeups are enabled then Core Standby will be used
instead.

ARM: mach-shmobile: sh7372 Core Standby Suspend-to-RAM
Add sh7372 Core Standby sleep mode support and tie it
in with the shared SH-Mobile ARM suspend code.
The Core Standby mode is the lightest sh7372-specific
sleep mode, cutting power to the ARM core excluding the
L2 cache. Any interrupt source can be used for wakeups.
The low level portion of this code is based on the
TI OMAP sleep code in sleep34xx.S, thanks to them.
