drm/vram-helper: Support struct drm_driver.gem_create_object
Drivers that what to allocate VRAM GEM objects with additional fields
can now do this by implementing struct drm_driver.gem_create_object.
v3:
* separately check allocation failure in if/else branches
before upcast to gbo
v2:
* only cast to gbo within if branch; set gbo directly
in else branch
