Currently when QEMU tries to migrate the macfb framebuffer it crashes randomly because the opaque provided by the DeviceClass vmsd property for both devices is set to MacfbState rather than MacfbNubusState or MacfbSysBusState as appropriate. Resolve the issue by adding new VMStateDescriptions for MacfbNubusState and MacfbSysBusState which embed the existing vmstate_macfb VMStateDescription within them using VMSTATE_STRUCT.
