Ability to switch between acpi_cpufreq and amd-pstate for recent Ryzen CPUs

This may or may not provide better performance, however it should help with power usage due to being able to clock much lower.

 

If I recall correctly, my 5600x on my Arch Linux install with acpi-cpufreq can clock around 2.2 GHz and its turbo of 4.85 Ghz, while with amd-pstate it's:

 

hardware limits: 550 MHz - 4.88 GHz
