This is a bit dangerous configuration IMHO.
Other architectures have some *real* governor selected by default, like Ondemand or Conservative. Running your CPUs at max (because of the default performance governor in arm64 config) may end up burning some SoCs accidentally just because their thermal stuff doesn't kick in to cool SoC down properly.
So, we should have one of ondemand, conservative and schedutil selected by default for arm64 as well IMO and schedutil is the one which every one is falling back to now a days, even android.
