The X-Powers AXP20X and AXP22X PMICs have multiple ADCs. They expose the
battery voltage, battery charge and discharge currents, AC-in and VBUS
voltages and currents, 2 GPIOs muxable in ADC mode and PMIC temperature.

This adds the device tree binding documentation for the X-Powers AXP20X
and AXP22X PMICs ADCs.

Use 'adc' for node name:

With that,
