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.
