drm/display: hdmi_state_helper: reject Audio IF updates if it's not supported 



Updating the InfoFrame if it can not be sent over the wire makes no
sense. Change drm_atomic_helper_connector_hdmi_update_audio_infoframe()
and drm_atomic_helper_connector_hdmi_clear_audio_infoframe() to return
an error if Audio InfoFrame callbacks are not implemented.
