[PATCH v2 1/2] ASoC: dt-bindings: es8316: Add regulator supplies

The ES8316 has separate AVDD, CPVDD, DVDD and PVDD supply inputs for its analog, charge pump, digital core and digital I/O domains. Describe all four inputs so boards can model the codec power topology. The binding also covers ES8311 and ES8323, whose supply inputs differ, so restrict these properties to the ES8316 compatible. Keep them optional for compatibility with existing descriptions.
