The Allwinner SoCs have a USB PHY controller that 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.

Perhaps this one should be split into multiple files. The oneOf's and 
if/then's are a bit much IMO.

You could always extract what's common and then $ref the common file.
