The MSI Raider A18 HX A9WJG has an internal digital microphone
connected through AMD ACP6x, but this machine does not expose the
AcpDmicConnected ACPI property, so acp_yc_mach does not bind.

Add a DMI quirk for this model.

This was tested on an MSI Raider A18 HX A9WJG with board MS-182L,
BIOS E182LAMS.31A, AMD ACP6x rev 0x62, and Realtek ALC274. After
applying the quirk, the internal microphone appears as an acp6x DMIC
capture device and records correctly.

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
