[Intel-gfx] [PATCH 2/2] drm/i915/tgl: Swap engines for rps (gpu reclocking)

If we disable rps, it appears the Tigerlake is stable enough to run
multiple engines simultaneously in CI. As disabling rps should only
cause the execution being slow, whereas many features depend on the
different engines, we would prefer to have the engines enabled while the
hangs are being debugged.
