This 3 non-atomic drivers all have the same function getting the only encoder available in the connector, also atomic drivers have this fallback. So moving it a common place and sharing between atomic and non-atomic drivers. While at it I also removed the mention of drm_atomic_helper_best_encoder() that was renamed in commit 297e30b5d9b6 ("drm/atomic-helper: Unexport drm_atomic_helper_best_encoder").
