media: v4l: vsp1: Integrate DISCOM in display pipeline
The DISCOM is used to compute CRCs on display frames. Integrate it in the display pipeline at the output of the blending unit to process output frames. Computing CRCs on input frames is possible by positioning the DISCOM at a different point in the pipeline. This use case isn't supported at the moment and could be implemented by extending the API between the VSP1 and DU drivers if needed.
