ASoC: Intel: avs: PCM operations for LNL-based platforms
Starting from LNL platform the so-called non-HDAudio transfer types,
e.g.: I2S/DMIC, utilize HDAudio LINK DMA rather than GPDMA for the data
streaming. In essence, all transfer types now utilize HDAudio Link. Most
of the existing code can be reused with the major difference being
HDAudio Link query method:
- fetch the Link by codec.addr in standard HDAudio transfer case
- fetch the Link by LEPTR.ID in non-HDAudio transfer case
To make the unification happen, store pointer to the Link in dma_data
and utilize it in the common code. And to avoid confusion in
transfer-type naming between cAVS-ACE 1.x (SkyLake till MeteorLake) and
ACE 2.0+ architecture (LunarLake onward), use:
- 'hda' for typical HDAudio transfer case
- 'nonhda' for non-HDAudio transfer case, cAVS-ACE 1.x
- 'althda' for non-HDAudio transfer case, ACE 2.0+
