superio/fintek: Add support for Fintek F81866AD-I

This patch adds support for the Fintek F81866AD-I SuperIO,
which is very similar to the fintek/f81865f.
This code adds some fan control support, inspired by fintek/f71869ad.
Furthermore its possible to change the temp sensor type (thermistor or diode).
