Matthew Auld d2cc01e179 drm/i915: apply PM_EARLY for non-GTT mappable objects 
On DG2 we allow objects that are smaller than the min_page_size, under
the premise that these are never mapped by the GTT, like with the paging
structures. Currently the suspend-resume path will try to map such
objects through the migration vm, which hits:

For now let's just force the memcpy path for such objects during
suspend-resume.
