PPC64: Partial fix to Linux crash: revert to old devfn 

Before 2e29bd0478, Uni-North host and AGP
bridge were using the same devfn, 11 << 3. The net effect was that only
AGP bridge was visible. This was changed in the commit to 13 << 3 for AGP.

Some of the later crashes happened due to NULL pointer dereferences generated
by 07b7d05377 and insufficient return value
checks.

Disable host device and revert AGP to 11 << 3.
