[PATCH] ASoC: amd: yc: Add DMI quirk for Lenovo V15 G6 ARP

[Daniel Ortiz]

The Lenovo V15 G6 ARP (product name 83UU) uses the ACP6x PDM interface
for its internal digital microphone array. Its firmware exposes neither
the AcpDmicConnected _DSD property nor the _WOV method, so acp6x_probe()
falls through to the DMI check and returns -ENODEV, leaving
acp_yc_mach.0 unbound and no capture device registered.

Add a DMI quirk entry for this model. With it, the machine driver binds
and the DMIC capture device is created:

  acp_yc_mach acp_yc_mach.0: Enabling ACP DMIC support via DMI
  card 2: acp6x [acp6x], device 0: DMIC capture dmic-hifi-0

Capture was verified working with arecord and PipeWire.
