CONFIG_DEVICE_PRIVATE cannot be selected in configurations
without ZONE_DEVICE:

WARNING: unmet direct dependencies detected for DEVICE_PRIVATE
  Depends on [n]: ZONE_DEVICE [=n]
  Selected by [y]:
  - DRM_NOUVEAU_SVM [=y] && HAS_IOMEM [=y] && DRM_NOUVEAU [=y] && MMU [=y] && STAGING [=y]
kernel/resource.c:1653:28: error: use of undeclared identifier 'PA_SECTION_SHIFT'
        size = ALIGN(size, 1UL << PA_SECTION_SHIFT);
kernel/resource.c:1654:48: error: use of undeclared identifier 'MAX_PHYSMEM_BITS'

Add a dependency for Nouveau to avoid broken randconfig builds.
