Subject: [PATCH v2 07/25] ARM: dtsi: axp22x: add AXP22X ADC subnode

X-Powers AXP22X PMIC has multiple ADCs, each one exposing data from the
different power supplies connected to the PMIC.

This adds the ADC subnode for AXP22X PMIC.

Signed-off-by: Quentin Schulz <quentin.schulz@...e-electrons.com>

v2:
 - removed #io-channels property (the IIO channels mapping is done by
 using iio_map structure in the ADC driver),
