[PATCH] x86_64: Revert k8-bus.c northbridge access change

As Travis Betak points out it accesses the wrong northbridge subfunction now. Switch back to the old code. Cc: "Travis Betak" <betak@mpdtxmail.amd.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
