[PATCH 3/6] pci: layerscape: limit fixup to layerscape controllers

[Sascha Hauer]

ls_pcie_fixup() assumes the fixed up device is attached to the layerscape
PCI controller. This may not be true when there's another controller
active in the system, so limit the execution of the fixup to the right
controller only.
