watchdog: sp805_wdt: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

This commit converts the deprecated SIMPLE_DEV_PM_OPS() to
DEFINE_SIMPLE_DEV_PM_OPS() and wraps the struct pointer. This allows the
removal of __maybe_unused annotations from the callbacks.

[Severity: Low]
Should this use pm_ptr() instead of pm_sleep_ptr() for the structure pointer?

According to the power management guidelines, dev_pm_ops structure pointers
should be wrapped with pm_ptr() rather than pm_sleep_ptr(). Using
pm_sleep_ptr() here drops the entire dev_pm_ops structure when CONFIG_PM_SLEEP
is disabled. If runtime PM callbacks are added to this structure in the future,
they will be incorrectly discarded even when CONFIG_PM is enabled.
