AP_Compass: support more external compasses on aerofc 

Let it probe on external bus. Aerofc has an HMC5883 on internal bus, but
we don't want it enabled as it interferes with the internal baro. Also
the rotation for the compass that comes with Aero RTF is different from
the other that got added later. That means people would need to orient a
third party IST8310-based compass differently on Aero RTF than on other
boards... that's a problem of having orientation based on the chip that
can't be solved on this commit.
