iio: ABI: Encourage differential voltage ABI usage

Browse source

So far, parts that could only do differential voltage measurements were
only required to have a consistent labeling of their channels by complying
either to voltageY or to voltageY-voltageZ ABI. Over time, code maintainers
came to the conclusion that the voltageY-voltageZ ABI is better suited for
differential-only chips as it provides a simple indication to users that
the channels measure the difference of two inputs.

Adjust the ABI documentation to recommend using the voltageY-voltageZ ABI
for chips that do only differential voltage measurements.
