[PATCH v2 1/3] dt-bindings: iio: adf4371: add differential ref

[Antoniu Miclaus <antoniu.miclaus@analog.com>]

Add support for enabling differential input reference.

By default the single-ended input is enabled.

Input frequency boundaries are change based on the mode selected
(single-ended/differential).
