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".

PVT controller has 5 VM (voltage monitor) sensors.

vm-map defines CPU core to VM instance mapping. A
