Revert "drm/etnaviv: Expose a few more chipspecs to userspace"
This reverts commit 1dccdba. In userspace a different approach was choosen - hwdb. As a result, there is no need for these values. Signed-off-by: Christian Gmeiner <cgmeiner@igalia.com> Reviewed-by: Tomeu Vizoso <tomeu@tomeuvizoso.net> Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
