hwmon: (pmbus/lm25066) Add regulator support
While these chips aren't strictly advertised as voltage regulators per se, they (aside from the lm25056) support the PMBus OPERATION command to enable and disable their outputs and have status bits for reporting various warnings and faults, and can hence usefully support all the pmbus_regulator_ops operations.
