From: Abhijeet Kumar <abhijeet.kumar@xxxxxxxxx>
When we change the resolution of DP pannel or hot plug-unplug it while
playing an audio clip,sometimes we observe a silent playback(no audio).
During no audio condition, we have noticed that the power state of the
pin or the connector is D3. Optimzing the way we set the power could
mitigate the issue.With this changes the verb is sent to set the power
state and response is received. Thus ensuring power state is set.
