hwmon: (f71882fg) Add support for the F81865F

Add support for the Fintek F81865F. It's essentially compatible with
the F71882FG, but has fewer inputs: 7 voltage, 2 temperature and 2 fan
inputs only.

           This driver can also be built as a module.  If so, the module
           will be called f71882fg.
