The saa7146-based hexium_gemini/orion and mxb drivers do not use the vb2
framework for streaming video, instead they use the old vb1 framework and
nobody stepped in to convert these drivers to vb2.
The hardware is very old, so the decision was made to remove them
altogether since we want to get rid of the old vb1 framework.
