Subject: [PATCH 1/2] dt-bindings: regulator: uniphier: Clean up clocks, resets, and their names using compatible string

Instead of "oneOf:" choices, use "allOf:" and "if:" to define clocks,
resets, and their names that can be taken by the compatible string.

The order of clock-names and reset-names doesn't change here.
