msm: acpuclock-8960: Update kraitv2 frequency to L2 mappings

Some power savings can be had by pairing different L2 frequencies
with cpu frequencies. Update the frequency tables accordingly. We
also thin out the available cpu frequencies so that only the max
frequency for a maximum voltage is used.
