Some tests (e.g. igt_vma_pin1) presume that we have a completely clean GGTT so that it can probe boundaries without fear that something is already allocated there. However, the mock device is starting to get complicated and following similar rules to the live device, i.e. we can't guarantee that i915->ggtt remains clean, so create a temporary address_space equivalent to the mock ggtt for the purpose.
