drm/sched: Create wrapper to add a syncobj dependency to job
In order to add a syncobj's fence as a dependency to a job, it is
necessary to call drm_syncobj_find_fence() to find the fence and then
add the dependency with drm_sched_job_add_dependency(). So, wrap these
steps in one single function, drm_sched_job_add_syncobj_dependency().
