To simplify code for system suspend, convert the .suspend|resume
callbacks into .suspend_late|resume_early. In general this could be
convenient for any driver that supports both system PM and runtime PM.
Move the runtime PM callbacks to be implemented within CONFIG_PM, to
make them available for system PM.
Use pm_generic_suspend_late_runtime and pm_generic_resume_early_runtime
as the new callbacks.
