The Allwinner A23 SoC and later have an embedded audio codec that uses a
separate controller to drive its analog part, which is supported in Linux,
with a matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.
