gpu: nvgpu: remove sync_fence dependencies from fence_gk20a

Browse Source 
Replaced all instances of sync_fence in gk20a_fence* code with
nvgpu_os_fence. Added the API install_fence for the nvgpu_os_fence
abstraction. sync_fence mechanism and its dependencies are completely
removed from the fence_gk20a methods. Due to the recent os_fence changes
and the changes to fence_gk20a, we can finally get rid of all the CONFIG_SYNCS
present in the submit path.
