hwmon: (pmbus/max20830): add VOUT feedback resistor scaling support
Implement support for external voltage divider scaling using the
adi,vout-rfb1-ohms and adi,vout-rfb2-ohms device tree properties.
When the desired output voltage exceeds VREF, a resistor divider
(RFB1 and RFB2) is used to scale down the feedback voltage. The
driver reads these resistor values from device tree and applies
the scaling formula: VOUT_actual = VOUT_measured × (1 + RFB1/RFB2)
The properties are optional. If not specified, the driver assumes
no voltage divider is present and reports the raw VOUT reading.
