hwmon: fix Abit Uguru3 driver detection on some motherboards 

This patch changes the driver to also detect uguru3's which hold 0x08 at DATA
initially, as has been reported here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=220160

Also when an uguru3's holds 0x0014 in the ID register it will now report
"Abit AB9 Pro" as motherboard identification.
