hwmon: add support for Fintek F71882FG and F71883FG

This is the second version of a new driver for the hardware monitoring features
of the Fintek F71882FG and F71883FG Super-I/O chips. This version has several
small fixes for flaws discovered during the review of the first version.

This version of the driver does not support the pwm part of these chips (yet).
I'll first design a sysfs api for this and post that for discussion, and then
implement pwm support as an incremental patch over this one.

This driver supports all sensors of this chip, except for the vid inputs. The
vid inputs are somewhat documented in the datasheet, but I know nothing about
vid/vrm stuff. Help with this would be much appreciated.
