[PATCH v2 35/47] arm: Register with kernel poweroff handler

From: Guenter Roeck
Date: Tue Oct 21 2014 - 00:14:53 EST

Register with kernel poweroff handler instead of setting pm_power_off
directly. Always use register_power_off_handler_simple as there is no
indication that more than one poweroff handler is registered.

If the poweroff handler only resets the system or puts the CPU in sleep mode,
select the fallback priority to indicate that the poweroff handler is one
of last resort. If the poweroff handler powers off the system, select the
default priority.

- Use defines to specify poweroff handler priorities
- Drop changes in arch/arm/mach-at91/setup.c (file removed upstream)
