ASoC: SOF: Intel: hda-dai: No need to decouple host/link DMA twice
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
There is no need to decouple a decoupled stream twice.
Keep the decoupling in hda_link_stream_assign() only as it is going to be
executed in all cases.
Drop the outdated comment from hda_link_dma_hw_params() as well since the code
has changed around it.
