drm/i915: DisplayPort hot remove notification to audio driver
commit 832afda6a7d7235ef0e09f4ec46736861540da6d upstream.
On DP monitor hot remove, clear DP_AUDIO_OUTPUT_ENABLE accordingly,
so that the audio driver will receive hot plug events and take action
to refresh its device state and ELD contents.
Note that the DP_AUDIO_OUTPUT_ENABLE bit may be enabled or disabled
only when the link training is complete and set to "Normal".
Tested OK for both hot plug/remove and DPMS on/off.
