nb/intel/pineview: Remove dead code in switch

This switch was likely copy-pasted from the one right above it. However,
the MEM_CLOCK_800MHz case isn't needed, since that is explicitly checked
and avoided before the while loop. With that gone, only the
667MHz/default case is left, which we don't need to switch over anymore.
