Konsta Holtta 1a4647272f 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).
