PM: Introduce new PMSG_POWEROFF event
PMSG_POWEROFF will be used for the PM core to allow differentiating between
a hibernation or shutdown sequence when re-using callbacks for common code.
Hibernation is started by writing a hibernation method (such as 'platform'
'shutdown', or 'reboot') to use into /sys/power/disk and writing 'disk' to
/sys/power/state.
Shutdown is initiated with the reboot() syscall with arguments on whether
to halt the system or power it off.
