superio/f71869ad: Add temperature sensor type 

This patch makes it possible to set the "Temperature Sensor Type Register"
at index 6Bh from the devicetree, allowing the use of thermistors instead of
BJT type sensors.

Register documentation (from page 60 of the F71869 datasheet):

6.6.25 Temperature Sensor Type Register - Index 6Bh
Bit 7-4: reserved
Bit 3: T3_MODE (0: thermistor, 1: BJT [default])
Bit 2: T2_MODE (0: thermistor, 1: BJT [default])
Bit 1: T1_MODE (0: thermistor, 1: BJT [default])
Bit 0: reserved
