As shown below, if a virtio PCI device is attached under a pci-bridge, the MR
of VirtIOPCIRegion does not belong to any address space. So memory_region_find
cannot be used to search for this MR.
Introduce the virtio-pci and pci_bridge address spaces to solve this problem.

As shown below, if a virtio PCI device is attached under a pci-bridge, the MR
of VirtIOPCIRegion does not belong to any address space. So memory_region_find
cannot be used to search for this MR.
Introduce the virtio-pci and pci_bridge address spaces to solve this problem.
