[PATCH v3 5/6] drm/v3d: Synchronous operations can't timeout

[Maíra Canal]

CPU jobs and CACHE CLEAN jobs execute synchronously once the DRM
scheduler starts running them. Therefore, there is no fence to wait on,
neither are those jobs able to timeout.

Hence, remove the `timedout_job` hook from the CPU and CACHE CLEAN
scheduler ops.
