hwmon: (f71882fg) Add F81968 support

Add hardware monitoring support for the Fintek F81968 Super I/O chip.
It is fully compatible with F81866.

Several products share compatibility with the F81866. To better distinguish
between them, ensure that the Product ID is displayed when the device is
probed.
