powerpc/4xx: Enable PCI domains on 4xx
Browse files Browse the repository at this point in the history
4xx chips commonly now have multiple PHBs, there is no reason to not
enable PCI domains on them. The main issue with PCI domains is X but
currently its already somewhat busted for other reasons such as the
36-bit physical address space, which I'm fixing separately.
