usb: dwc3: exynos: Use DEFINE_SIMPLE_DEV_PM_OPS for PM functions

Browse Source 
This macro has the advantage over SIMPLE_DEV_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.
