Instead of punching a hole in the linear mapping, just use normal cachable memory, and apply the flush sequence documented in the CPC625 (aka U3) user manual. This allows us to remove quite a bit of code related to the early allocation of the DART and the hole in the linear mapping. We can also get rid of the copy of the DART for suspend/resume as the original memory can just be saved/restored now, as long as we properly sync the caches.
