[PATCH v2] drm/sti: clean up after drm_atomic_helper_shutdown rework

From: Benjamin Gaignard
Date: Thu Oct 18 2018 - 05:03:48 EST


Since drm_atomic_helper_shutdown() rework it is possible to do additional
clean up in sti driver: custom plane destroy functions become useless and
clean up encoder is no more needed.

version 2:
- try to be more smart when unbinding tvout.
