PM / Runtime: Implement the pm_generic_runtime functions for CONFIG_PM
The pm_generic_runtime_suspend|resume functions were implemented within
CONFIG_PM_RUNTIME.
As we also may use runtime PM callbacks during system suspend, to put
devices into low power state, we need to move the implementation of
pm_generic_runtime_suspend|resume to CONFIG_PM.
This change gives a power domain provision to invoke a platform
driver's runtime PM callback from a power domain's system PM callback.
This were earlier prevented by the platform bus, since it uses the
pm_generic_runtime_suspend|resume functions as runtime PM callbacks.
