PM / devfreq: exynos: Use DEFINE_SIMPLE_DEV_PM_OPS for PM functions
This macro has the advantage over SET_SYSTEM_SLEEP_PM_OPS that we don't have to care about when the functions are actually used. Also make use of pm_sleep_ptr() to discard all PM_SLEEP related stuff if CONFIG_PM_SLEEP isn't enabled.
