As per suggestion from Yinghai Lu <yinghailu@gmail.com> this patch
fixes the problems with PCI add-on cards not being detected or
initialized on MCP55-based systems (PCI bridge decoding change).

I have tested this on the MSI MS-7260 (K9N Neo) with a PCI VGA card,
which worked fine in any of the three PCI slots.
