ASoC: codecs: es8316: Add regulator support

Browse source

ES8316 has separate AVDD, CPVDD, DVDD and PVDD supply inputs.

Request and enable the supplies during I2C probe, before initializing
the regmap. Keep them enabled for the lifetime of the I2C device so the
regmap cannot access an unpowered device and its cache remains
synchronized if the ASoC component is unbound and rebound.
