drm/i915: HDMI hot remove notification to audio driver
commit 2deed761188d7480eb5f7efbfe7aa77f09322ed8 upstream.
On HDMI monitor hot remove, clear SDVO_AUDIO_ENABLE accordingly, so that
the audio driver will receive hot plug events and take action to refresh
its device state and ELD contents.
The cleared SDVO_AUDIO_ENABLE bit needs to be restored to prevent losing
HDMI audio after DPMS on.
