[PATCH v4 16/18] ARM: dtsi: axp22x: add battery power supply subnode

[Quentin Schulz]

The X-Powers AXP22X PMIC exposes battery supply various data such as
the battery status (charging, discharging, full, dead), current max
limit, current current, battery capacity (in percentage), voltage max
limit, current voltage, and battery capacity (in Ah).

This adds the battery power supply subnode for AXP22X PMIC.

v2:
 - changed DT node name from battery_power_supply to
 battery-power-supply,
 - removed io-channels and io-channel-names from DT (the IIO mapping is
 done in the IIO ADC driver now),
