drm/connector: hdmi: allow disabling Audio Infoframe

Add drm_atomic_helper_connector_hdmi_disable_audio_infoframe(), an API
to allow the driver disable sending the Audio Infoframe. This is to be
used by the drivers if setup of the infoframes is not tightly coupled
with the audio functionality and just disabling the audio playback
doesn't stop the HDMI hardware from sending the Infoframe.
