ASoC: Intel: mtl-match: Add CDB35L56-EIGHT-C 8x CS35L56 without CS42L43

This adds a match entry for using all the amps on a CDB35L56-EIGHT-C board
without the CS42L43 codec. Configuration is:

  SDW0: 4x CS35L56 (OUT1, OUT2, OUT3, OUT4)
  SDW1: 4x CS35L56 (OUT5, OUT6, OUT7, OUT8)

Speaker playback and amp feedback are aggregated.
