dt-bindings: iio: adc: Add common-mode-channel property

Browse source

There are ADCs that are differential but support to measure single-ended
signals on the same channels by connecting a constant voltage to the
negative input pin.

This property allows to properly define a single-ended channel that
requires two inputs to be specified. Software can use the presence of
this property to mark the channel as not differential.
