Switch over to virtio_instance_init_common. Drop duplicate properties in virtio-gpu-pci and virtio-vga as they are properly aliased now. Also drop the indirection via DEFINE_VIRTIO_GPU_PROPERTIES, we don't need it any more as the properties are defined in a single place now. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
