drm/nouveau/nv1a,nv1f/disp: fix memory clock rate retrieval

commit 24bf7ae359b8cca165bb30742d2b1c03a1eb23af upstream.

Based on the xf86-video-nv code, NFORCE (NV1A) and NFORCE2 (NV1F) have a
different way of retrieving clocks. See the
nv_hw.c:nForceUpdateArbitrationSettings function in the original code
for how these clocks were accessed.
