Thread-topic:	[Xen-devel] [PATCH 1/2] VT-d: pci code cleanup

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.
