mn10300/PCI: Remove useless pcibios_last_bus
pcibios_last_bus was apparently copied from x86. On mn10300, it is statically initialized to -1 and may be set with the "pci=lastbus=<X>" boot option, but it is never tested. This patch removes everything related to pcibios_last_bus. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
