#1416083 — [PATCH v2 11/20] drm: sti: Rely on the default ->best_encoder() behavior

All outputs 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() implementations and let the core call
drm_atomic_helper_best_encoder() for us.
