Subject: [PATCH 36/44] mips: Register with kernel poweroff handler

Register with kernel poweroff handler instead of setting pm_power_off
directly.

If there is an indication that there can be more than one poweroff handler,
use register_poweroff_handler, otherwise use register_poweroff_handler_simple
to register the poweroff handler.

If the poweroff handler only resets or stops the system, select a priority of
0 to indicate that the poweroff handler is one of last resort. If the poweroff
handler powers off the system, select a priority of 128, unless the poweroff
handler installation code suggests that there can be more than one poweroff
handler and the new handler is only installed conditionally. In this case,
select a priority of 64.
