ASoC: amd: yc: Add DMI quirk for Acer Aspire AG14-22P

The Acer Aspire AG14-22P has its internal microphone connected to the
ACP as a digital microphone, but the BIOS does not advertise it via the
AcpDmicConnected ACPI property, so the internal microphone does not work
out of the box. Add a DMI quirk to enable it.

Tested on an Aspire AG14-22P (board Dove2_MDU, BIOS V1.03): the acp6x
DMIC card is created and the internal microphone captures audio.
