drm/nouveau/dmem: device memory helpers for SVM
Device memory can be use in SVM, in which case we do not have any of the existing buffer object. This commit add infrastructure to allow use of device memory without nouveau_bo. Again this is a temporary solution until a rework of GPU memory management. Signed-off-by: Jérôme Glisse <jglisse@redhat.com>
