gpu: nvgpu: remove fence dependency tracking
In preparation for better abstraction in job synchronization, drop support for the dependency fences tracked via submit pre-fences in semaphore-based syncs. This has only worked for semaphores, not nvhost syncpoints, and hasn't really been used. The dependency was printed in the sync framework's sync pt value string. Remove also the userspace-visible gk20a_sync_pt_info which is not used and depends on this feature (providing a duration since the dependency fence's timestamp).
