This series extends the hwmon PMBus driver for the MPS MPQ8785 to support
two additional Monolithic Power Systems devices: the MPM82504 and
MPM3695 family.

The driver is restructured to support multiple devices using device tree
matching. It also introduces an optional
"mps,vout-fb-divider-ratio-permille" property to configure the
VOUT_SCALE_LOOP PMBus register, which adjusts reported output voltages
depending on the external feedback divider.

Device tree bindings are updated accordingly.

Changes have been tested on hardware with device-tree based matching
using the MPM82504 and MPM3695-10.
