dt-bindings: gpu: samsung: re-order entries to match coding convention

The Devicetree bindings coding convention, as used in most of the files
and expressed in Documentation/devicetree/bindings/example-schema.yaml,
expects "allOf:" block with if-statements after "required:" block.

Re-order few schemas to match the convention to avoid repeating review
comments for new patches using existing code as template. No functional
changes.
