[PATCH] nova-core: Ada: basic GPU identification

[John Hubbard <jhubbard@nvidia.com>]

...which is sufficient to make Ada GPUs work, because they use the
pre-existing Ampere GPU code, unmodified.

Tested on AD102 (RTX 6000 Ada).

Signed-off-by: John Hubbard <jhubbard@nvidia.com>

This applies cleanly to today's drm-rust-next.

thanks,
John Hubbard
