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.

IIRC, audio infoframes are mandatory if you send audio over the cable,
so maybe we should do like you did for drmm_connector_hdmi_init and
error in drm_connector_hdmi_audio_init if we don't have the proper
write_infoframe hook set?

HDMI hosts can be sending Audio InfoFrames in some other way (think
about LT9611UXC, which manages infoframes on its own).
