I don't really like this change, the ifdef hackery is disgusting and
then we are putting that in a completely different part of the kernel.
There are at least these two ways of solving this, maybe more:
- Fix the bl switcher driver and add the complexity in it (which you
tried to do earlier).
- Add a cpufreq flag to skip arch-set-freq-scale call.
