powerpc/spufs: add atomic busy_spus counter to struct cbe_spu_info

Browse source

As nr_active counter includes also spus waiting for syscalls to return
we need a seperate counter that only counts spus that are currently running
on spu side. This counter shall be used by a cpufreq governor that targets
a frequency dependent from the number of running spus.
