Add regulator support for the four ES8316 power domains so board
descriptions can model and control the codec supplies.

The binding patch documents AVDD, CPVDD, DVDD and PVDD as optional
supplies for ES8316, preserving compatibility with existing device-tree
descriptions. The driver patch enables the supplies before initializing
the regmap and keeps them enabled for the lifetime of the I2C device.

The missing supply model was identified while reviewing the RubikPi 3
audio support:

Changes in v2:
- Restrict the supply properties to the ES8316 compatible.
- Enable the regulators before regmap initialization and keep them enabled
  for the lifetime of the I2C device.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
