The av7110 driver does not use the vb2 framework for streaming video, instead it uses the old vb1 framework and nobody stepped in to convert this driver to vb2. The hardware is very old, so the decision was made to remove it altogether since we want to get rid of the old vb1 framework. The last remaining files of this driver are removed in this patch.
