hwmon: pmbus: mpq8785: Add support for MPM3695 family
Add support for the Monolithic Power Systems MPM3695 family.
It contains four devices with suffixes: -10, -20, -25 and -100.
The device is PMBus compliant and shares characteristics with the
MPM82504.
MPM3695-25 has different VOLTAGE_SCALE_LOOP register size [11:0]
and therefore needs to have a separate compatible entry.
Tested with device tree based matching (MPM3695-10).
