PCI/IA64: embed pci hostbridge resources into pci_root_info
Currently, pcibios_resource_to_bus() and pcibios_bus_to_resource() functions use pci_host_bridge to translate bus side address from/to cpu side address. The pci_window in pci_controller never be used again. So we remove pci_window in pci_controller and embed hostbridge resource into pci_root_info. Bjorn suggested to implement hostbridge resources release in IA64 like in X86, this patch is to prepare for that.
