sbc8548: delete unused MPC8548CDS info carried over from port
There are a couple defines and PCI bridge quirks related to the PCI backplane of the MPC8548CDS that have no meaning in the context of the port to the sbc8548 board, so delete them. Also, the form factor of the sbc8548 is a standalone board with a single PCI-X and a single PCI-e slot. That pretty much guarantees that it will never be a PCI agent itself, so the host/agent and root complex/end node distinctions have been removed. Similarly, since there is no physical connector mapping to PCI2, so all references of PCI2 in the board support files have been removed as well.
