Subject: [PATCH] ASoC: hdac_hdmi: Ensuring proper setting of output widget
 power state

In usecases like hot plug-unplug DP panel or modeset during a playback,
sometimes we observe no audio after codec resets.

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.
