devices: add ISL68220 support

This is a PMBus power-management voltage regulator employed
in a variety of systems.  The Linux hwmon subsystem includes
a driver for it that exposes current, voltage, power and
temperature readings.

Tested: on an machine, sensor readings appear on
dbus via the psusensor daemon as expected.
