Use performance governor to avoid frequency scaling (#973)

Browse Source 
After running HAOS on my ODROID N2+ several hours I see freezes and
sometimes stack traces which point to a problem in CPU frequency
scaling. This crash seems not to appear on Hardkernel's 18.04 Ubuntu
stable release. However, Hardkernel's Ubuntu uses the performance
governor. Use the performance governor as well to avoid crashes on N2+.
