If the watchdog is part of a dedicated power domain (as it may be on
RZ/G3S) the watchdog PM domain need to be powered on in the watchdog
restart handler. Currently, only the clocks are enabled in the watchdog
restart handler. To be able to also power on the PM domain we need to
call pm_runtime_resume_and_get() on the watchdog restart handler, mark
the watchdog device as IRQ safe and register the watchdog PM domain
with GENPD_FLAG_IRQ_SAFE.

Register watchdog PM domain as IRQ safe. Along with it the always-on
PM domain (parent of the watchdog domain) was marked as IRQ safe.
