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.
