This updates the cpufreq drivers in arch/powerpc so they build again
after the core cpufreq changes that broke them in commit
in835481d9.

This patch adds a cpufreq governor that takes the number of running spus
into account. It's very similar to the ondemand governor, but not as complex.
Instead of hacking spu load into the ondemand governor it might be easier to
have cpufreq accepting multiple governors per cpu in future.
Don't know if this is the right way, but it would keep the governors simple.
