watchdog: imx2_wdt: Remove __maybe_unused notations

Browse Source 
Use the DEFINE_SIMPLE_DEV_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 __maybe_unused notation.
