[PATCH v4 14/18] mfd: axp20x: add MFD cells for AXP20X and AXP22X battery driver

[Quentin Schulz]

The X-Powers AXP20X and AXP22X PMICs can have a battery as power supply.

This patch adds the AXP20X/AXP22X battery driver to the MFD cells of the
AXP209, AXP221 and AXP223 MFD.

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),
