ALSA: hda/hdmi: fix i915 silent stream programming flow
The i915 display codec may not successfully transition to normal audio streaming mode, if the stream id is programmed while codec is actively transmitting data. This can happen when silent stream is enabled in KAE mode. Fix the issue by implementing a i915 specific programming flow, where the silent streaming is temporarily stopped, a small delay is applied to ensure display codec becomes idle, and then proceed with reprogramming the stream ID.
