The driver is restructured to support multiple devices using device tree matching. It also introduces an optional "voltage-scale-loop" 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 both the MPM82504 and MPM3695-10.
