drm/i915: Convert intel_tv connector properties to atomic, v5.
intel_tv has properties that are handled in the atomic core, but needs a modeset to update the properties inside the connector. The detect(), get_mode() and mode_valid() probe callbacks also depend on the connector state, which made this a good connector to convert first. It helped find all the issues when converting connectors to atomic. Because of these requirements, connector atomic_check() was added and connection_mutex is held during probing. The diffstat looks more favorable now. :) Changes since v1: - Add intel_encoder->swap_state to allow updating connector state. - Add intel_tv->format for detect_mode and mode_valid, updated on atomic commit. Changes since v2: - Fix typo in tv_choose_preferred modes function name. - Assignment of tv properties is done in core, so intel_tv only needs a atomic_check function. Thanks Ville! Changes since v3: - connection_mutex is now held in mode_valid() and get_modes(), this removes the need for caching parts of the connector_state. Changes since v4: - Use the new atomic connector check function.
