The setup-bus code doesn't work correctly for configurations with more than one display adapter in the same PCI domain. This stuff actually is a leftover of an early 2.4 PCI setup code and apparently it stopped working after some "bridge_ctl" changes. So the best thing we can do is just to remove it and rely on the fact that any firmware *has* to configure VGA port forwarding for the boot display device properly. But then we need to ensure that the bus->bridge_ctl will always contain valid information collected at the probe time, therefore the following change in pci_scan_bridge() is needed.
