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_power_off_handler, otherwise use register_power_off_handler_simple
to register the poweroff handler.
If the poweroff handler only resets or stops the system, 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,
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, install the handler with low priority.
