Qiang Yu 7f60c4b9d9 drm/lima: add trace point for tasks
track lima task start which can be combined with
dma_fence_signal to identify task execution time.

example command to record:

trace-cmd record -i \
  -e "lima:lima_task_submit" -e "lima:lima_task_run" \
  -e "*fence:*fence_signaled" -e "drm:drm_vblank_event" \
  -e "drm:drm_vblank_event_queued" sleep 4
