pci: Add interface names to hybrid PCI devices
The following devices support both PCI Express and Conventional PCI, by including special code to handle the QEMU_PCI_CAP_EXPRESS flag and/or conditional pcie_endpoint_cap_init() calls: * vfio-pci (is_express=1, but legacy PCI handled by vfio_populate_device()) * vmxnet3 (is_express=0, but PCIe handled by vmxnet3_realize()) * pvscsi (is_express=0, but PCIe handled by pvscsi_realize()) * virtio-pci (is_express=0, but PCIe handled by virtio_pci_dc_realize(), and additional legacy PCI code at virtio_pci_realize()) * base-xhci (is_express=1, but pcie_endpoint_cap_init() call is conditional on pci_bus_is_express(dev->bus) * Note that xhci does not clear QEMU_PCI_CAP_EXPRESS like the other hybrid devices Cc: Dmitry Fleytman <dmitry@daynix.com> Cc: Jason Wang <jasowang@redhat.com> Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Alex Williamson <alex.williamson@redhat.com> Cc: "Michael S.
