pwm: samsung: Use DEFINE_SIMPLE_DEV_PM_OPS for PM functions
This macro has the advantage over SIMPLE_DEV_PM_OPS that we don't have to
care about when the functions are actually used, so the corresponding
#ifdef can be dropped.
Also make use of pm_ptr() to discard all PM related stuff if CONFIG_PM
isn't enabled.
