[PATCH] drm/nouveau: Add missing fb SLCG registers for kepler2

[Lyude Paul <lyude@redhat.com>]

Somehow I didn't manage to notice this the last time I looked at my
mmiotraces, these seem to be all valid registers.

Forwarding this to stable, as there's a small chance that not having
these could cause clockgating to be unstable.
