To be clear the main reason I'm querying this is that it doesn't appear
to be a _DSD based binding at all (as far as I understand it, the API
it's using is from before the dawn of time or at least the dawn of git).

Given the design of _DSD is to share with DT and we already have device
tree bindings for the device we should be using, it's not clear to me if
we want to grind them all through UEFI and I suspect they'd be unhappy
if we tried but pretty much all audio CODECs are good candidates for use
with ACPI given the new hardware designs Intel have so if we are doing
it I ought to be bouncing everyone to UEFI forum.
