Add mmap callback to struct drm_gem_object_funcs, which is supposed to handle the vma setup. It will be used by both normal fops->mmap (via drm_gem_mmap_obj()) and prime mmap (via drm_gem_prime_mmap()).
For starters the shmem and vram helpers are switched over to the new workflow, to show things in action for review.
