[media] cx25821: remove video output support
The video output functionality never worked for this driver. Now remove the creation of the output video nodes as well to prevent users from thinking that video output is available, when it isn't. To correctly implement this the video output should use vb2 as well, and that requires rewriting the output DMA setup. But without hardware to test I am not able to do that.
