sh: SuperH Mobile suspend support
This patch contains CONFIG_SUSPEND support to the SuperH architecture. If enabled, SuperH Mobile processors will register their suspend callbacks during boot. To suspend, use "echo mem > /sys/power/state". To allow wakeup, make sure "/sys/device/platform/../power/wakeup" contains "enabled". Additional per-device driver patches are most likely needed.
