Enable powersave CPU frequency governor (#4346)

Browse Source 
The CPUfreq governor "powersave" sets the CPU statically to the lowest
frequency within the borders of scaling_min_freq and scaling_max_freq.
This can be useful if a particular power budget should not ever be
crossed. Can be set using `cpufreq.default_governor=powersave`. Note
that this obviously affects performance.
