drm/sun4i: don't add components that are already in the queue Even though the components framework can handle duplicate entries, the extra entries cause a lot more debug messages to be generated, which would be confusing to developers not familiar with our driver and the framework in general. Instead, we can scan the relatively small queue and check if the component to be added is already queued up. Since the display pipelines are symmetrical (not considering the third display pipeline on the A80), and we add components level by level, when we get to the second instance at the same level, any shared downstream components would already be in the queue.
