[PATCH v1 1/4] dt-bindings: iio: adc: Add MediaTek MT6359 PMIC AUXADC

Add a new binding for the MT6350 Series (MT6357/8/9) PMIC AUXADC,
providing various ADC channels for both internal temperatures and
voltages, audio accessory detection (hp/mic/hp+mic and buttons,
usually on a 3.5mm jack) other than some basic battery statistics
on boards where the battery is managed by this PMIC.

+description:
+ The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found
+ in some MediaTek PMICs, performing various PMIC related measurements
+ such as battery and PMIC internal voltage regulators temperatures,
+ accessory detection resistance (usually, for a 3.5mm audio jack)
+ other than voltages for various PMIC internal components.
