drm/vc4: hdmi: Reset audio infoframe on encoder_enable if previously streaming

Browse source

If the encoder is disabled and re-enabled (eg mode change) all infoframes
are reset, whilst the audio subsystem know nothing about this change.
The driver therefore needs to reinstate the audio infoframe for
itself.
