[0/2] Allow detecting ACP6x DMIC via _DSD

Message

It's not possible to probe for the presence of a DMIC, so the ACP6x
machine driver currently has a hardcoded list of all the systems known
to have a DMIC connected to the ACP.

Although this design works it means that the acp6x driver needs to always
grow with more systems and worse, if an OEM introduces a new system there
will be a mismatch in time that even if the driver (otherwise) works fine
it needs their system added to the list to work.

So this series introduces a _DSD that OEMs can populate into the BIOS to
indicate presence of a DMIC.

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
