dt-bindings: mfd: Convert Allwinner GPADC bindings to a schema
The Allwinner SoCs have an embedded GPADC that is doing thermal reading as
well, 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.
