drm/v3d: Add more tracepoints for V3D GPU rendering.
The core scheduler tells us when the job is pushed to the scheduler's queue, and I had the job_run functions saying when they actually queue the job to the hardware. By adding tracepoints for the very top of the ioctls and the IRQs signaling job completion, "perf record -a -e v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty decent timeline.
