drm/amdgpu: Remove default best_encoder hook from DC 

For atomic driver this is the default, no need to reimplement it. We
still need to keep the copypasta for not-atomic drivers though, since
no one polished the legacy crtc helpers as much as the atomic ones.

v2: amdgpu uses ->best_encoder internally, give it a local copy. It
might be a good idea to merge the connector and encoder into one
amdgpu_dm_sink structure, that might match DC internals better. At
least for non-DPMST outputs. Kudos to Ville for spotting this.

v3: Rebase onto a487411a64 ("drm/amd/display: Use DRM helper for
best_encoder").
