virtualization: Add virtio-video driver as external module.
This driver should conform WIP spec v3 [1] with some updates for spec v4
[2], and, some unspecified features such as VIRTIO_VIDEO_DEVICE_CAMERA.
Imported from internal OpenSynergy's revision:
bcc33b6b9e0156b381a70c54d2df02c57b63d270
Kernel was configured with necessary features for this driver:
enable MEDIA_SUPPORT
disable MEDIA_SUBDRV_AUTOSELECT
enable MEDIA_PLATFORM_SUPPORT
enable VIDEO_VIRTIO
Keep driver as an external module to simplify future updates.
