[PATCH 13/20] drm: tegra: Rely on the default ->best_encoder() behavior

[Boris Brezillon]

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() implementation and let the core call
drm_atomic_helper_best_encoder() for us.
