cpu/intel/speedstep: Have nb and sb code provide c5/c6/slfm
C5, C6 and slfm depend on the southbridge and the northbridge to be able
to provide this functionality, with some just lacking the possibility to
do so. Move the devicetree configuration to the southbridge.
This removes the need for a magic lapic in the devicetree.
