Janne Hellsten 9148a1e627 gpu: nvgpu: gk20a: Optimize gpfifo entry copy ...

Use memcpy for copying gpfifo inputs into the gpfifo ring buffer.
This speeds up one command buffer heavy benchmark from 82 FPS to 86
FPS.  Speed up is due to a) faster memory move and b) zero tracing
overhead when PB tracing is disabled.
