ASoC: intel: sof_sdw: Add support for cs42l43-cs35l56 sidecar amps
The cs42l43 has both a SPI master and an I2S interface, these can
be used to populate 2 cs35l56 amplifiers as sidecar devices along
side the cs42l43. Giving a system that looks like:
+-----+ +---------+ <- SPI -> +---------+
| CPU | <- SDW -> | CS42L43 | | CS35L56 |
+-----+ +---------+ <- I2S -> +---------+
Add a quirk to specify this feature is present and use it to add
codec to codec DAI link to connect the amplifiers into the sound
card, add appropriate widgets, and setup clocking on the
amplifiers.
