Enable overclock :
- Add new frequencies up to 1.7 GHz
- Remove PLL2 limitation
- Set cpu clock to 1 Ghz at boot
governors :
 - lulzactive bug in suspend mode found: this governor register early_suspend in __init function so early_suspend is registered at boot; thus this function is called each time system enter suspend mode, even if lulzactive governor is not enabled. Secondary registers/unregisters have been move from __init function to START and STOP cases of main lulzative function. This bug is also present in smartass2 but had minor effect because of more guards, but removed stil.
 - major corrections on lulzactive governor to make it fully runnable on Xperia LT15i and LT18i devices
 - minor corrections on smartass2 to improve kernel stability
 - note : this early_suspend bug might be present on other governors written from Interactive or Smartass governors
