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

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

[Rodnei Cilto via B4 Relay]

From: Rodnei Cilto <rcilto1@lenovo.com>

The Lenovo V15 AMN G6 (product name 83VD and 84CS) uses the ACP6x PDM
interface for its internal digital microphone array.

Its firmware exposes neither the AcpDmicConnected _DSD property
nor the _WOV method, causing acp6x_probe() to fall through to
the DMI check and return -ENODEV. As a result, acp_yc_mach.0
is not bound and no capture device is registered.

Add a DMI quirk entry for this model. With it, the machine
driver binds correctly and the DMIC capture device becomes
available.

Capture was verified working with arecord and PipeWire.
