commit 90219f1bd273055f1dc1d7bdc0965755b992c045 upstream.
With IPC3, we reset hw_params during the stop trigger, so we should also
clean up the link DMA during the stop trigger.
Cc: <stable@xxxxxxxxxxxxxxx> # 6.4.x
Fixes: 1bf83fa6654c ("ASoC: SOF: Intel: hda-dai: Do not perform DMA cleanup during stop")
Closes: https://github.com/thesofproject/linux/issues/4455
Closes: https://github.com/thesofproject/linux/issues/4482

Note that many recent Intel based laptops are affected.
Added missing code for 6.4 kernels to keep the fix simple not depending
on the other changes. This commit is present in 6.5 tree already.
