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. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
