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.

[1/1] ASoC: amd: yc: Add DMI quirk for Acer Aspire AG14-22P

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
