Several HDMI drivers have common code pice in the .mode_valid function that validates RGB / 8bpc rate using the TMDS char rate callbacks. Move this code piece to the common helper and remove the need to perform this check manually. In case of DRM_BRIDGE_OP_HDMI bridges the check can be dropped in favour of performing it in drm_bridge_connector.
