[PATCH 2/2] power: supply: axp20x: Use devm_iio_channel_get_sys() for iio chans

[Chris Morgan <macroalpha82@gmail.com>]

From: Chris Morgan <macromorgan@hotmail.com>

Since commit e37ec3218870 ("mfd: axp20x: Allow multiple regulators")
the drivers for AC, battery, and USB have failed to probe when the
option of CONFIG_AXP20X_ADC is enabled. This appears to be because
the existing function devm_iio_channel_get() no longer calls
iio_channel_get_sys(). Use the newly created function of
devm_iio_channel_get_sys() instead.

Fixes: e37ec3218870 ("mfd: axp20x: Allow multiple regulators")
