i9300: downclock more aggressively
previously, pegasusq would keep 3 or 4 cores active with static content on the screen tweak the governor's values so that sometimes we get down to 1 core active with screen on, both by increasing the on/off clock speeds/rq sizes of secondary cores, bumping up_threshold and encouraging faster downclocking.
