[CPUFREQ] More misc cleanups.

- CPUFREQ_ALL_CPUS is not a valid argument any more, don't mention it
  in include/linux/cpufreq.h
- without a driver->init() function a cpufreq driver isn't even
  loaded, so remove that check in the per-CPU initialization
- whitespace and clarification changes to linux/cpufreq.

All from Dominik again..
