hwmon/f71805f: Add support for the Fintek F71872F/FG chip 

Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the
same as the Fintek F71805F/FG as far as hardware monitoring is concerned,
with two additional internal voltages monitored (VSB and battery), and 6
VID inputs (not yet supported.)

To make things a bit more confusing, two of the voltage input pins (in4
and in8) can be used for other functions. The driver reads the pin
configuration from the Super-I/O configuration space to decide whether
it must create interface files for these inputs or not.

Many thanks to Nikolay Derkach for testing the early iterations of this
code and reporting bugs.

The Fintek F71872F/FG Super I/O chip is almost the same, with two

6 VID inputs. The VID inputs are not yet supported by this driver.
The driver assumes that no more than one chip is present, which seems
reasonable.

The two LSB of the voltage limit registers are not used (always 0), so
you can only set the limits in steps of 32 mV (before scaling).
