drm/atomic-helper: Add atomic_enable plane-helper callback
Add atomic_enable to struct drm_plane_helper_funcs. It enables a
plane independently from updating the plane's content. As such, it is
the inverse of the atomic_disable plane helper. Useful for hardware
where plane enable state is independent from plane content.
