gpu: nvgpu: drop user callback support in CE

Browse Source 
Simplify the copyengine code by deleting support for the
ce_event_callback feature that has never been used. Similarly, create a
channel without the finish callback to get rid of that Linux dependency,
and delete the finish callback function as it now serves no purpose.

Delete also the submitted_seq_number and completed_seq_number fields
that are only written to.
