From: Gustavo Padovan gustavo.padovan@collabora.co.uk
Now that the value of fence and the timeline are not stored by sw_sync anymore we can remove this extra abstraction to retrieve this data.
This patch changes both fence_ops (.fence_value_str and .timeline_value_str) to return the str directly.
It also clean up struct sync_timeline_ops by removing both ops from there.
