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

[Jetha Chan <jethachan@gmail.com>]

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.
