i9300: initial pegasusq powerhal
* based off flo * powersave (3 core max/1GHz), balanced (current defaults), and performance (back off on downscaling) * support for separate low power profiles (activated on screen off) PS2: low power + min/max cpu freq support PS3: whitespace fixes PS4: apparently POWER_HINT_LOW_POWER means PROFILES[POWER_SAVE].
