dt-bindings: hwmon: (mr75203) fix "intel,vm-map" property to be optional

Change "intel,vm-map" property to be optional instead of required.

The driver implementation indicates it is not mandatory to have
"intel,vm-map" in the device tree:
 - probe doesn't fail in case it is absent.
 - explicit comment in code - "Incase intel,vm-map property is not
   defined, we assume incremental channel numbers".
