cleaning up acpuclock-8627

so when i took a look at your frequency table i have no idea what happened there, maybe you just forgot to clean up but the l2 caches were using non existing 7th bus speeds , and will definitely affect any of the cpu freqs with an l2 of 15 so i cleaned it up and  added underclock to 162khz and overclock to 1.7ghz ,,, please test stability and let me know
