ASoC: amd: yc: Add Alienware m15 R7 AMD to DMIC quirk table

Browse source

The Alienware m15 R7 AMD exposes an ACP6x DMIC path, but its DMI
product name is not present in the Yellow Carp ACP quirk table. As a
result, the ACP machine driver does not enable the DMIC card on this
system.

Add the DMI product name for this machine. With this quirk applied, the
kernel reports:

  acp_yc_mach acp_yc_mach.0: Enabling ACP DMIC support via DMI

and ALSA exposes the ACP DMIC capture device:

  card 3: acp6x
  device 0: DMIC capture dmic-hifi-0

Tested on an Alienware m15 R7 AMD with product SKU 0B59.
