drm/vram-helper: turn on PRIME import/export
We don't populate drm_driver.gem_prime_import_sg_table so only
DMA-BUFs exported from our own device can be imported. We don't
populate drm_gem_object_funcs.get_sg_table so DMA-BUFs cannot be
imported into another device. Still, this is useful to user-space
to share buffers between processes and between API boundaries
(e.g. wlroots hard-requires PRIME import/export support).
