Add devicetree support so that consumers can reference the channels
via devicetree, especially the power subdevice can make use of that
to provide voltage_now properties.  

Does the mapping vary from board to board?  Often these mappings are
internal to the chip so might as well be provided hard coded in the
relevant drivers rather than via DT. See drivers that have iio_map
structure arrays.

Most things are internal to the chip, but 
AIN1/AIN0 are external and could be connected to anything.

Andreas
