This might require a little more explanation, because the PCIe 
controlers are (relative to the base of the axi at 18000000 node) at 
0x12000, 0x13000 and 0x14000 respectively, which are all within the 1MiB 
aperture defined from 0x18000000.

The PCIe node(s) do not currently have a "ranges" node either, so I am 
not sure what this change does besides flattening the address space?
