hwmon: Add support for newer uGuru's
This patch adds a new driver for the hardware monitoring features of the third revision of the Abit uGuru chip, found on recent Abit motherboards. This is an entirely different beast then the first and second revision (its again a winbond microcontroller, but the "protocol" to talk to it and the bank addresses are very different.
