The kernel core now supports a notifier call chain for system
restart functions.
With this change, the arm_pm_restart callback is now optional,
so check if it is set before calling it. Only call the notifier
functions if arm_pm_restart is not set.

v4: No change.
v3: Use wrapper function to execute notifier call chain.
v2: Only call notifier call chain if arm_pm_restart is not set.
Do not include linux/watchdog.h.
