ASoC: Intel: mtl-match: Add CDB35L56-EIGHT-C with aggregated speakers

This adds a match for the CDB35L56-EIGHT-C board with SmartCodec and
SmartAmp speakers aggregated.

The configuration is:

  SDW0: CS35L56 x2 (SmartAmp) using OUT1 and OUT2
  SDW1: CS35L56 x2 (SmartAmp) using OUT7 and OUT8
  SDW3: CS42L43 (SmartJack, SmartMic, SmartAmp)

CS35L56 and CS42L43 Speaker playback is aggregated across all 3 buses.

The device addresses and reset arrangements of the EIGHT-C board are
quirky hence the use of non-contiguous outputs OUT1,2,7,8.
