x86: multi pci root bus with different io resource range, on 64-bit
scan AMD opteron io/mmio routing to make sure every pci root bus get correct
resource range. So later pci scan could assign correct resource to device
with unassigned resource.
this some kind make up for system without _CRS for multi pci root bus.
