MIPS: PCI: Remove unused busn_offset
pci_add_resource_offset() is for host bridge windows where the bridge translates CPU addresses to PCI bus addresses by adding an offset. To my knowledge, no host bridge translates bus numbers, so this is only useful for MEM and IO windows. In any event, host->busn_offset is never set to anything other than zero, so pci_add_resource() is sufficient. a2e50f53d535 ("MIPS: PCI: Add a hook for IORESOURCE_BUS in pci_controller/bridge_controller") also added busn_resource itself. This is currently unused but may be used by future SGI IP27 fixes, so I left it there.
