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

Browse Source 
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.
