The nec-usb-xhci device (which is a USB3 controller) has always presented itself as a PCI device when plugged into a legacy PCI slot, and a PCIe device when plugged into a PCIe slot, but libvirt has always auto-assigned it to a legacy PCI slot. This patch changes that behavior to auto-assign to a PCIe slot on systems that have pcie-root (e.g. Q35 and aarch64/virt). Since we don't yet auto-create pcie-*-port controllers on demand, this means a config with an nec-xhci USB controller that has no PCI address assigned will also need to have an otherwise-unused pcie-*-port controller specified: <controller type='pci' model='pcie-root-port'/> <controller type='usb' model='nec-xhci'/> (this assumes there is an otherwise-unused slot on pcie-root to accept the pcie-root-port)
