Add sh7372 specific code to power down unused pm domains.
This should really be replaced by some generic PM core
code IMO, but until that happens this patch makes sure
we don't waste power by leaving unused power domains on.

Add support for the sh7372 A3SG power domain. This domain contains
the SGX hardware block, but there is no open source driver available.

This patch ties in the previously added sh7372 sleep
mode known as Core Standby together with the shared
SH-Mobile ARM CPUIdle implementation.

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.
