[PATCH 04/20] drm: exynos: Rely on the default ->best_encoder() behavior

[Boris Brezillon]

We have 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.
