107ba59fc6 nouveau: remove a few function stubs 
nouveau_dmem_migrate_vma and nouveau_dmem_convert_pfn are only called
when CONFIG_DRM_NOUVEAU_SVM is enabled, so there is no need to provide
!CONFIG_DRM_NOUVEAU_SVM stubs for them.

5be73b6908 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.
