PCI/x86: don't assume prefetchable ranges are 64bit
We should not assign 64bit ranges to PCI devices that only take 32bit
prefetchable addresses.
Try to set IORESOURCE_MEM_64 in 64bit resource of pci_device/pci_bridge
and make the bus resource only have that bit set when all devices under
it support 64bit prefetchable memory. Use that flag to allocate
resources from that range.
