Subject: [PATCH v1 2/2] ASoC: Intel: soc-acpi-intel-mtl-match: Add match for CDB35L63-CB2

From: Richard Fitzgerald <rf@...nsource.cirrus.com>

This adds a match entry for using all the amps on a CDB35L63-CB2 board
without the CS42L43 codec. Configuration is:

  SDW3: 1x CS35L63 (OUT1)
  SDW1: 1x CS35L63 (OUT2)

Speaker playback and amp feedback are aggregated.
