Make pci bar assigner preferchable memory aware. This is needed for PCI bridge support because memory space and prefetchable memory space is filtered independently based on memory base/limit and prefetchable memory base/limit of pci bridge. On bus 0, such a distinction isn't necessary so keep existing behavior by checking bus=0.
pci_bios_io_addr = 0xc000; pci_bios_mem_addr = BUILD_PCIMEM_START;

How can we be sure that the "mem" space doesn't overlap with the "prefmem" space?
