revert "hwmon: f71882fg: add support for the Fintek F71808E"

Revert commit 7721fea3d0fd93fb4d000eb737b444369358d6d3 ("hwmon:
f71882fg: add support for the Fintek F71808E").

Hans said:

: A second review after I've received a data sheet for this device from
: Fintek has turned up a few bugs.
:
: Unfortunately Giel (nor I) have time to fix this in time for the 2.6.36
: cycle.  Therefor I would like to see this patch reverted as not having any
: support for the hwmon function of this superio chip is better then having
: unreliable support.
