Revert "Revert "Disable extra CPUs during Nanobench""

This reverts commit 43307c09b97c5a5c5174f0c4ccb79bdaf3ebf557.

Reason for revert: Fixed this time.  Echo 1 > already online cpu
returns exit code 1, which makes python over-react.

> Original change's description:
> > Disable extra CPUs during Nanobench
> >
> > The previous experiment revealed that nanobench can
> > run on any of the online CPUs, so rather than put
> > the ones we don't need/want into powersave mode, just
> > disable them.
> >
> > Maybe in the future we can run CPU tests on the big
> > or LITTLE cpus to get perf data on higher end or
> > lower end cpus, but only if we get very stable
> > results from this.
