[PATCH v3 1/4] dt-bindings: iio: adc: mediatek,mt6359-auxadc: add mt6323 PMIC AUXADC

From: Roman Vivchar <rva333 at protonmail.com>

The MediaTek mt6323 PMIC includes an AUXADC used for battery voltage,
temperature, and other internal measurements. The IP block is not
register-compatible with mt6359 and should use a separate driver.

Add the devicetree binding documentation and the associated header file
defining the ADC channel constants.

Also change the description to 'MT6350 series and similar' because
the binding already includes more than mt635x series PMICs.

Finally, add the MAINTAINERS entry for the header with ADC constants.
