[PATCH v2 5/8] drm/v3d: Use DRM_GPU_SCHED_STAT_NO_HANG to skip the reset

[Maíra Canal]

When a CL/CSD job times out, we check if the GPU has made any progress
since the last timeout. If so, instead of resetting the hardware, we skip
the reset and allow the timer to be rearmed. This gives long-running jobs
a chance to complete.

Use the DRM_GPU_SCHED_STAT_NO_HANG status to skip the reset and re-arm
the timer.
