[PATCH] PCI: remove PCI_BRIDGE_CTL_VGA handling from setup-bus.c

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.
