The driver uses crtc_* fields from the mode. While I think in the enable-path this would be correct, I do not think it's correct in the check phase, as the crtc hasn't had a chance to update the crtc_* fields yet. Overall, my understanding is that the crtc_* fields are relevant only in cases where we have things like interlace or double pixel mode, where we have a logical and real timings. We never use those with DSI, so the crtc_* fields should just always match the normal values. So, drop the use of crtc_* values.
