dt-bindings: hwmon: (pmbus/max20830): add VOUT feedback resistor properties and complete examples

Browse source

Add adi,vout-rfb1-ohms and adi,vout-rfb2-ohms properties to support
external voltage divider configuration for VOUT sensing. When the
desired output voltage is higher than VREF, a resistor divider (RFB1
and RFB2) is required to reach the intended value.

The properties use a dependency constraint to ensure both resistors
are specified together, or neither. This prevents misconfiguration
where only one resistor value is provided.

This patch also adds missing entries in the examples.
