media: vivid: drop overlay support
Destructive overlay support (i.e. where the video frame is DMA-ed
straight into a framebuffer) is effectively dead. It was a
necessary evil in the early days when computers were not fast enough
to copy SDTV video frames around, but today that's no longer a problem.
It requires access to the framebuffer memory, which is a bad idea and
very hard to do safely. In addition, in drm it is today almost
impossible to get hold of the framebuffer address.
So drop support for this.
