Subject: [PATCH v3 05/17] dt-bindings: iio: adc: ad7768-1: document regulator provider property

The AD7768-1 provides a buffered common-mode voltage output
on the VCM pin that can be used to bias analog input signals.

Add regulators property to enable the use of the VCM output,
referenced here as vcm_output, by any other device.

Signed-off-by: Jonathan Santos <Jonathan.Santos@...log.com>
---
v3 Changes:
* VCM is now provided as a regulator within the device, instead of a 
  custom property.

v2 Changes:
* New patch in v2.
