vfio: Implement PciDevice Trait for vfio device
According to kernel Documents/vfio.txt and Documents/vfio-mediated-device.txt,user pass host assigned device or mdev to crosvm through --vfio parameter, vfio module open this device and get this device's information. Implement PciDevice trait on this device, then vfio_pci module could trap guest pci cfg r/w and mmio r/w, and transfer this operation into kernel vfio. Currently the relationship of vfio container:group:device are 1:1:1, in the future it could extend to 1:m:n.
