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.

v3: fix using new DEFINE_SIMPLE_DEV_PM_OPS PM macro hence
change the $subject and the commit message
v2: add __maybe_unused to suspend/resume functions in case CONFIG_PM
is disabled.
