Subject: [PATCH 08/20] drm: msm: Rely on the default ->best_encoder() behavior where appropriate

For all outputs except DSI we have a 1:1 relationship between connectors
and encoders and the driver is relying on the atomic helpers: we can
drop the custom ->best_encoder() and let the core call
drm_atomic_helper_best_encoder() for us.
