Creating or filling pci-OF-bus-map property in the device-tree is deprecated since May 2006 [1] and was used only in old platforms like PowerMac. Currently kernel code handles it only for chrp and powermac code. So completely disable filling pci-OF-bus-map property for non-chrp and non-powermac platforms.
