Subject: [PATCH v2 22/25] ARM: dtsi: axp209: add battery power supply subnode

The X-Powers AXP209 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
and min limits, current voltage, and battery capacity (in Ah).

This adds the battery power supply subnode for AXP20X PMIC.

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

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),
