ASoC: SOF: Intel: pci-tgl: unblock S5 entry if DMA stop has failed"
If system shutdown has not been completed cleanly, it is possible the DMA stream shutdown has not been done, or was not clean. If this is the case, Intel TGL/ADL HDA platforms may fail to shutdown cleanly due to pending HDA DMA transactions. To avoid this, detect this scenario in the shutdown callback, and perform an additional controller reset. This has been tested to unblock S5 entry if this condition is hit.
