sh: hibernation support
Add Suspend-to-disk / swsusp / CONFIG_HIBERNATION support
to the SuperH architecture.
To suspend, use "swapon /dev/sda2; echo disk > /sys/power/state"
To resume, pass "resume=/dev/sda2" on the kernel command line.
The patch "pm: rework includes, remove arch ifdefs V2" is
needed to allow the generic swsusp code to build properly.
Hibernation is not enabled with this patch though, a patch
setting ARCH_HIBERNATION_POSSIBLE will be submitted later.
