[v4,00/16] SoundWire/ASoC: add SDW BPT/BRA support

Message

This series adds support for SoundWire BPT/BRA. The change is mainly on
the SoundWire tree. It is better to go through the SoundWire tree with
Mark's Acked-by tag.

v2:
 - Add MODULE_DESCRIPTION in the "ASoC: SOF: Intel: hda-sdw-bpt: add
   helpers for SoundWire BPT DMA" patch.

v3:
 - Change sdw_cdns_write_pdi1_buffer_size and
   sdw_cdns_read_pdi0_buffer_size to static values.

v4:
 - Revise bra.rst as suggested.
