watchdog: PM: use DEFINE_SIMPLE_DEV_PM_OPS and pm_sleep_ptr for dev_pm_ops

Replace the deprecated SIMPLE_DEV_PM_OPS with DEFINE_SIMPLE_DEV_PM_OPS.
This also drops the __maybe_unused annotations on the suspend/resume
callbacks, since pm_sleep_ptr() inside the new macro already handles
the case where CONFIG_PM_SLEEP is disabled. Wrap the dev_pm_ops
assignment with pm_sleep_ptr() so the entire dev_pm_ops structure
is dropped when CONFIG_PM_SLEEP is disabled, instead of leaving
it as a dead struct with NULL callbacks.
