* DOC: atomic plane helpers

* The functions here are used by the atomic plane helper functions to
* implement legacy plane updates (i.e., drm_plane->update_plane() and
* drm_plane->disable_plane()). This allows plane updates to use the
* atomic state infrastructure and perform plane updates as separate
* prepare/check/commit/cleanup steps.
