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.
