hwmon: (mr75203) add VM active channel support

Browse source

Add active channel support per voltage monitor.
The number of active channels is read from the device-tree.
When absent in device-tree, all channels are assumed to be used.

This shall be useful to expose sysfs only for inputs that are connected
to a voltage source.

Setting number of active channels to 0, means that entire VM sensor is
not used.
