powerpc/spufs: add atomic busy_spus counter to struct cbe_spu_info
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.
