CPUFreq Scaling Tests With AMD's Kaveri On Linux 3.16

With Warsow the only performance difference was found when using the powersave governor where the frame-rate had dropped compared to the other three tested governors.

The powersave governor when running Warsow led to the system power use being lower by about 10% compared to the ondemand governor.

The performance-per-Watt though averages out across the four CPUfreq governors.

The Xonotic story is similar to the other gaming/graphics tests.
