[PATCH] ASoC: SOF: intel: hda: Clean up link DMA for IPC3 during stop

[Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx>]

From: Ranjani Sridharan <ranjani.sridharan@xxxxxxxxxxxxxxx>

With IPC3, we reset hw_params during the stop trigger, so we should also
clean up the link DMA during the stop trigger.

Fixes: 1bf83fa6654c ("ASoC: SOF: Intel: hda-dai: Do not perform DMA cleanup during stop")
