[PATCH 6.19 232/844] hwmon: (f71882fg) Add F81968 support

[Sasha Levin]

From: "Ji-Ze Hong (Peter Hong)" <peter_hong@xxxxxxxxxxxxx>

[ Upstream commit e4a3d6f79c9933fece64368168c46d6cf5fc2e52 ]

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.
