Allow device probing to recognise the Fintek F71808E.

Sysfs interface:
 * Fan/pwm control is the same as for F71889FG
 * Temperature and voltage sensor handling is largely the same as for
   the F71889FG
  - Has one temperature sensor less (doesn't have temp3)
  - Misses one voltage sensor (doesn't have V6, thus in6_input refers to
    what in7_input refers for F71889FG)

For the purpose of the sysfs interface fxxxx_in_temp_attr[] is split up
such that it can largely be reused.
