[PATCH 8/8] watchdog: wdat_wdt: Remove #ifdef guards for PM related functions

[Paul Cercueil]

Use the new NOIRQ_SYSTEM_SLEEP_PM_OPS() and pm_sleep_ptr() macros to
handle the .suspend/.resume callbacks.

These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use #ifdef guards. Not using #ifdef guards means that the code is
always compiled independently of any Kconfig option, and thanks to that
bugs and regressions are easier to catch.
