This series adds basic PCI device enumeration in Xen. This will allow us to not rely on Dom0 enumeration for supported controllers, which will enable PCI passthrough for dom0less setups.
Enumeration is disabled by default and can be enabled with "pci-scan" cmdline option. Discovered devices are added to Xen and assigned to dom_io by default.
