[RESEND PATCH v4 5/9] ARM: dtsi: axp209: add AC power supply subnode

[Quentin Schulz <quentin.schulz@free-electrons.com>]

The X-Powers AXP20X PMIC exposes the status of AC power supply, the
current current and voltage supplied to the board by the AC power
supply.

This adds the AC power supply subnode for AXP20X PMIC.

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