hwmon: (pmbus) Add regulator supply into macro

Browse Source 
Add regulator supply into PWBUS_REGULATOR macro. This makes it optional
to define a vin-supply in DT. Not defining a supply will add a dummy
regulator supply instead and only cause the following debug output:

```
Looking up vin-supply property in node [...] failed
```
