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.
