The Devicetree bindings coding convention, as used in most of the files
and expressed in Documentation/devicetree/bindings/example-schema.yaml,
expects:
1. "allOf:" block just before "properties:" (or after "required:" for
more complex cases),
2. additionalProperties/unevaluatedProperties at the end of the file,
just before the examples section.
Re-order few schemas to match the convention to avoid repeating review
comments for new patches using existing code as template. No functional
changes.
