Arto Merilainen of NVIDIA confirmed that we should increment syncpoint
after each HW trigger because it might be not safe to adjust registers
while operation hasn't completed yet, let's do it.
Some time ago Arto mentioned on IRC that multiple syncpoint increments may cause premature increment, so maybe this patch is not valid after all. I haven't noticed any problems yet, but we need to keep it in mind.
