mb/asrock/g41m-vs3-r2: Allow to set the fixed duty cycle from rtc nvram

By default the SuperIO is strapped to set the fan duty cycle of the CPU fan to a
100%, which can be quite loud. This change makes it configurable.

This duty cycle will remain fixed afterwards but with w83627ehf linux module +
the fancontrol tool you can gain fine grained control. No proper fan control can
be implemented with the SuperIO's modes of operation as it seems that none of
the temps are correlated with the CPU temp (even in vendor BIOS). Newer ACPI
revisions might make this possible to implement this without the fancontrol
daemon.

This also fixes sensors 2 to thermistor mode (not the default diode mode).
