PCI/IA64: SN: remove sn_pci_window_fixup()
Currently, pcibios_bus_to_resource() and pcibios_resource_to_bus()
functions use pci_host_bridge_window in pci_host_bridge to translate
bus side to/from cpu side addresses. Pci_window in pci_controller
under IA64 is no used again, so it's no need to use sn_pci_window_fixup()
to setup pci_window again, remove it.
