watchdog/core: Provide interface to stop from poweroff()
PARISC has a a busy looping power off routine. If the watchdog is enabled
the watchdog timer will still fire, but the thread is not running, which
causes the softlockup watchdog to trigger.
Provide a interface which allows to turn the watchdog off.
