radeonsi: disable the constant engine (CE) on Carrizo and Stoney
It must be disabled until the kernel bug is fixed, and then we'll enable CE based on the DRM version. Cc: 12.0 13.0 <mesa-stable@lists.freedesktop.org> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com> (cherry picked from commit 31f988a9d6d05f4aaea4d0455e509a5f6b667d9c)
