As a final paranoid step (we _should_ have reset the GPU on suspending
the device prior to unload), reset the GPU once more before removing the
powercontext and other related power saving paraphernalia.
A clue that this may not be the case is

during rapid fault-injection reloads. 0xcc is POISON_FREE_INIT which
suggests that the system cleared the pages on initialisation as they are
still being used from the previous module load.
Despite that we also have a couple of GPU resets prior to this...
I have a sneaky suspicion that may be a GuC artifact.
