gpu: nvgpu: Use busy looping for flush operations
Use busy looping for l2 tag flush and elpg flush
operations. This is making total flash time more
accurate and reduced overall time compared with
usleep. Also added trace points to measure
performance for these operations.
Also corrected timeout error check for non-silicon
platforms.
