ASoC: SOF: Extend ChainDMA and DSPless mode to LNL+
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
For both ChainDMA and DSPless mode the requirement is that the link must
be serviced by HD-DMA.
On pre Lunar Lake platforms this was only valid for HDAudio links but with
Lunar Lake all link types now serviced by HD-DMA.
This allows us to enable ChainDMA and DSPless mode for SoundWire links as
well.
