This disables all ISP blocks, and makes the rkisp1 display input data from the mipi csi receiver at the output, unmodified. To determine whether we can activate bypass, we can detect whether both the source and sink formats are YUV. If they are, we can set a new in_bypass flag. For YUV bypass, we should configure the ISP input to interpret incoming H/VSYNC signals as data enable / disable. Add this.
