This patch moves the pci code from iommu.c to pci.c. Instead of setup pci hierarchy in array bus2bridge in iommu_context_mapping, use scan_pci_devices once to add all existed PCI devices in system to alldevs_list and setup pci hierarchy in array bus2bridge. In addition, implement find_upstream_bridge to find the upstream PCIe-to-PCI/PCIX bridge or PCI legacy bridge for a PCI device, therefore it''s cleanly to handle context map/unmap for PCI device, even for source-id setting.
