ASoC: codecs: nau8822: add support for supply regulators
NAU8822 has four power supply pins: VDDA, VDDB, VDDC, and VDDSPK, which
need to be online and stable before communication with the device is
attempted.
Request and enable these regulators at init time, if provided. Also wait
for 100 us after powering up the supply regulators before attempting to
access the device registers, as recommended by the datasheet.
This helps avoid -ENXIO errors when the codec is probed before the
regulators are ready.
