01cf9d52 ("microblaze/PCI: Support generic Xilinx AXI PCIe Host Bridge
IP driver") removed pcibios calls to:

  pcibios_setup_bus_self()
  pcibios_setup_bus_devices()

Given that pcibios_fixup_bus() was the only caller of those functions they
have now become dead code (along with the functions they were calling in
turn), so they can be removed.
