[v2,34/52] dt-bindings: sunxi: Add CPU Configuration Controller Binding

Commit Message

Even though we've used the CPU configuration driver for some time and a
number of boards using it already, we never had a binding for it. Let's
add it based on what the driver expects and the boards are providing.
