[PATCH v3 03/14] regulator: dt-bindings: max77802: Document of_compatible for regulator

[Krzysztof Kozlowski]

Document new required property for regulator driver: of_compatible.
The property allows MFD core to bind the driver to node with regulators
and this simplifies parsing regulators init data from DTS
