The DP display driver issues an audio disconnect notification
after the video disconnect notification. Sometimes audio driver
is waiting for the video commit to complete before turning off
the audio engine. In such cases, there is a brief screen freeze
observed on the primary. In other cases, when the off call from
audio driver gets delayed, a momentary screen freeze is seen.
The audio notification happens as part of the display commit call.
The order of notification is video and then audio while
processing display connect and the same order is followed for
disconnect also, which is causing this issue. These changes will
modify the order of notification to send audio disconnect first
and then video while processing DP cable disconnect.

Skip the wait in the disable path if the audio engine has already
been disabled or was not previously enabled. This avoids an
unnecessary wait since the audio subsystem will only acknowledge
the notification and not request a tear down if no audio playback
was started by the user.

Add a check to ensure that audio registers are programmed only
when the DP timing engine (audio session) is enabled. This will
reduce the likelihood of un-clocked register access for audio
related operations.
