From: Liam Beguin <redacted>

Add bindings documentation describing per channel reference voltage
selection.
This adds the adi,internal-ref-microvolt property, and child nodes for
each channel. This is required to properly configure the ADC sample
request based on which reference source should be used for the
calculation.
