dt-bindings: iio: adc: Add single-channel property
Devices that have both single-ended channels and differential channels
cause a bit of confusion when the channels are configured in the
devicetree.
Clarify difference between these two types of channels for such devices
by adding single-channel property alongside diff-channels. They should
be mutually exclusive.
Devices that have only single-ended channels can still use reg property
to reference a channel like before.
