libcamera: pipeline: rkisp1: Use SOF event to warn about late parameters
In the Timeline approach the idea was to delay queuing buffers to the device until the IPA had a chance to prepare the parameters buffer. A check was still added to warn if the IPA queued buffers before the parameters buffer was filled in. This check happened much sooner then needed as the parameter buffers does not have to be ready when the buffer is queued but just before it's consumed. As the pipeline now has true knowledge of each SOF we can move the check there and remove the delaying of queuing of buffers. This change really speeds up the IPA reactions as the delays used in the Timeline where approximated while with this change they are driven by events reported by the device.
