    Impact: fix AMD Family 11h boot hangs / USB device problems
    
    The AMD Fam11h CPUs have a K8 northbridge. This northbridge is different
    from other family's because it lacks GART support (as I just learned).
    
    But the kernel implicitly expects a GART if it finds an AMD northbridge.
    
    Fix this by removing the Fam11h northbridge id from the scan list of K8
    northbridges. This patch also changes the message in the GART driver
    about missing K8 northbridges to tell that the GART is missing which is
    the correct information in this case.
