I don't see how your driver handles probe or suspend ordering, so I
don't think this is correct approach.
Handling of the watchdog requires poking PMU, thus the watchdog device
node must have reference to the PMU node. Removing it from DTS makes the
hardware representation incomplete, beside mentioned driver issue.
