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.
