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.

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).
