gpu: nvgpu: abstract submit profiling

Browse Source 
Add gk20a_fifo_profile_snapshot() to store the submit time in a
profiling entry that was acquired from gk20a_fifo_profile_acquire().
Also get rid of ifdef CONFIG_DEBUG_FS by stubbing the acquire and free
functions when debugfs is not enabled. This reduces some cyclomatic
complexity in the submit path.
