[PATCH V2 01/15] iio: adc: axp20x_adc: Add adc_en1 and adc_en1 to axp_data

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

Add the register for adc_en1 and adc_en2 to the axp_data struct. This
allows us to specify a different register to enable the adc channels
for different devices such as the AXP717.
