acpuclock-8064 : added 81mhz, increase l2 bus

Adding 81mhz to the core, in order to get more low power consumption
when idle, and added some freqs to help smoothing cpu-scaling.

Taken into account an initial l2 bus increase, from mako bedalus'
"increase lower freq bus, can give more fps so it will reducing the
needs of higher speed freq, thus conserving more battery and reducing
heats generated"
