[ Upstream commit a79efc44b51432490538a55b9753a721f7d3ea42 ]
The video_device for the MPEG encoder did not set device_caps.
Add this, otherwise the video device can't be registered (you get a WARN_ON instead).
Not seen before since currently 417 support is disabled, but I found this while experimenting with it.
