drm: rz-du: Ensure correct suspend/resume ordering with VSP
The VSP serves as an interface to memory and a compositor to the DU. It
therefore needs to be suspended after and resumed before the DU, to be
properly stopped and restarted in a controlled fashion driven by the DU
driver. This currently works by chance. Avoid relying on luck by
enforcing the correct suspend/resume ordering with device links.
Based on similar work done by Laurent Pinchart for R-Car DU.
