This allows iteration over encoders without requiring connection_mutex. Changes since v1: - Add a set_best_encoder helper function and update encoder_mask inside it. Changes since v2: - Relax the WARN_ON(!crtc), with explanation. - Call set_best_encoder when connector is moved between crtc's. - Add some paranoia to steal_encoder to prevent accidentally setting best_encoder to NULL.
