ASoC: SOF: Intel: pci-tgl: unblock S5 entry if DMA stop has failed"

[ Upstream commit 69c9b02931158421f46463e3a36e72092412f6c6 ]

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.
