Use devm_register_power_handler() that replaces global pm_power_off
variable and allows to register multiple power-off handlers. It also
provides restart-handler support, i.e. all in one API.

When I boot with (most of) this patchset applied, I get the warning at
kernel/reboot.c:187:

	/*
	 * Handler must have unique priority. Otherwise call order is
	 * determined by registration order, which is unreliable.
	 */
	WARN_ON(!atomic_notifier_has_unique_priority(&restart_handler_list, nb));

As the NTXEC driver doesn't specify a priority, I think this is an issue
to be fixed elsewhere.

Other than that, it works and looks good, as far as I can tell.

Thank you. You have conflicting restart handlers, apparently NTXEC
driver should have higher priority than the watchdog driver. It should
be a common problem for the watchdog drivers, I will lower watchdog's
default priority to fix it.

The watchdog subsystem already uses "0" as default priority, which was
intended as priority of last resort for restart handlers. I do not see
a reason to change that.
