[PATCH] hwmon: Fix for first generation Abit uGuru chips

Now that the abituguru driver is seeing some more widespread testing
it has turned out that one the first generation of Abit uGuru
motherboards, with uGuru revision 1, the autodetect bank1 sensor type
code doesn't (always) work. This patch adds a module param to override
the autodetect, and it adds validity checks for the value of the 2
other autodetection override module params. An example of howto use
the new param can be found here:
