radeonfb: Let hwmon driver probe the "monid" I2C bus

Browse Source 
Some Radeon cards have an I2C-based thermal sensor chip connected to
the "monid" I2C bus. Set the I2C probing class of this bus properly so
that hwmon drivers can detect devices on it and bind to them.

This closes kernel.org bug #26172.

We exclude PPC for the time being, as Benjamin doesn't want us to
mess up with them without explicit testing, and there is no evidence
that this change is needed for them either.
