From: Ville Syrjälä <ville.syrj...@linux.intel.com>
encoder->disable() is supposed to happen before the pipe/transcoder
gets disabled. The icl+ DSI code screwed that up and put most things
(including the transcoder disable itself) into encoder->disable().
Follow the common rules and hoist most things into the
encoder->post_disable() hook.
