Issue 695: gpadc-iio driver for TWL6037

Reported by Nikolaus Schaller, Aug 20, 2015

we now have a working gpadc driver but need one that provides an iio 
user space interface.

Then, we can make the twl4030-madc-battery driver more universal:
* it is not really dependent on twl4030 so get rid of the reference 
in the name
* it is not really madc dependent
* what we need are just some iio channels and an adc device we can 
specify to get voltages and currents from

Contains link(s) to a gpadc-iio implementation.
