drm/i915: Factor out i915_ggtt_suspend_vm/i915_ggtt_resume_vm()
Factor out functions that are needed by the next patch to suspend/resume
the memory mappings for DPT FBs.
No functional change, except reordering during suspend the
ggtt->invalidate(ggtt) call wrt. atomic_set(&ggtt->vm.open, open) and
mutex_unlock(&ggtt->vm.mutex). This shouldn't matter due to the i915
suspend sequence being single threaded.
