Revert "Update SIMPLE GPU"

This reverts commit c331f2beefd0446dedd964fdf9c05fdf9009fd75.
Revert "Revert "KGSL: Simple Governor: so I kinda butchered in a good way of course the original code from faux, but the simplicity is still here. Added an history so that we can track the average do that the frequency scaling is much more proporcional to the actual GPU load rather than having is ramp up every now and then due to spurious load spike. Also remove two useless ifs.""

This reverts commit 43ccd9e1cacef796ba0ac0f6fa949ae1af1aed2f.
