[PATCH 1/3] ASoC: SOF: Intel: hda-dai: Do not perform DMA cleanup during stop

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

In the case of repeated start/stop without involving hw_free, the stream
tag needs to be preserved for the subsequent starts. So, skip performing
the DMA clean up during stop and handle it only during suspend or
hw_free.
