watchdog: omap: Remove #ifdef guards for PM related functions
Use the pm_ptr() macro to handle the .suspend/.resume callbacks.
This macro allows 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.
