CPUFreq Governor Tuning For Better AMD Ryzen Linux Performance

With the Tesseract game was one of the few instances where the CPUfreq governor made a noticeable difference in the performance between the five tested governors. The performance governor did the best followed by schedutil and then ondemand.

But when it comes to performance-per-Watt, it's a toss-up between ondemand/schedutil/conservative.

When using the powersave governor, it was noticeably slower than the other governors.

The powersave governor was also much slower than the others for LAME MP3 encoding.
