ALSA: hda/hdmi: disable KAE for Intel DG2 

Use of keep-alive (KAE) has resulted in loss of audio on some A750/770
cards as the transition from keep-alive to stream playback is not
working as expected. As there is limited benefit of the new KAE mode
on discrete cards, revert back to older silent-stream implementation
on these systems.
