[PATCH v3 08/19] dt-bindings: hwmon: (mr75203) add "moortec,vm-active-channels" property

Add optional "moortec,vm-active-channels" property to define the number
of active channels per VM.

This shall be useful to avoid exposing sysfs for reading inputs that are
not connected to any voltage source.

V3 -> V2:
- Add "moortec" prefix to property name.
- Add explanation why this change is needed.
