dt-bindings: mfd: dlg,da9063: document voltage monitoring
Document that the da9063 only provides under- *and* over-voltage monitoring in one, and therefore requires both to be configured with the same severity and value. Add an example for clarification.

description: |
For device-tree bindings of other sub-modules refer to the binding documents
under the respective sub-system directories.
+ Using regulator-{uv,ov}-{warn,error,protection}-microvolt requires special
+ handling: First, when GP_FB2 is used, it must be ensured that there is no
+ moment where all voltage monitors are disabled. Next, as da9063 only supports
+ UV *and* OV monitoring, both must be set to the same severity and value
+ (0: disable, 1: enable).
