ASoC: cs35l56: Add DAI for SDCA OT25 stream

Browse source

Add a DAI for the SDCA OT25 stream on SoundWire DP4.

The SDCA-defined OT25 stream is an amp reference feedback, typically used
for AEC. The firmware outputs this on DP4. The firmware owns all control
registers for this stream so there are no mixer controls or any other
configuration options.
