dt-bindings: clocks: Convert Allwinner A80 USB clocks to a schema
The Allwinner A80 SoC has a USB clocks 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.
