Subject: [PATCH v2 19/25] iio: adc: axp20x_adc: map battery IIO channels

This maps the IIO channels batt_v, batt_chrg_i and batt_dischrg_i
(respectively exposing the current charging and discharging currents and
current voltage measures of the battery power supply) to the battery
power supply driver.
