igt/pm_rps: Replace arbitrary HIGH_LOAD blit with a busyspin
Using a blit + sleep does not guarantee generating a high enough load to
keep the GPU busy, a busyspin does. Replace the blit at high load with a
continuous series spins and low load with a mix of spin and sleep.
v2: Maintain a limited queue depth
