CPUFreq Governor Tuning For Better AMD Ryzen Linux Performance

First up with the older Portal game, there wasn't much of a difference in the performance aside from powersave being slightly slower than schedutil/ondemand/performance while conservative was the slowest at around only a third of the speed of the other governors.

With Counter-Strike: Global Offensive, the performance governor had a minor lead over the other governor options.

The performance-per-Watt with CS:GO ended up being quite close between the governor choices with Linux 4.10.

With the lighter ET: Legacy game, powersave and conservative were notably lower than ondemand/performance/schedutil.

While the performance-per-Watt results weren't too dramatic.
