cpufreq: zzmoove governor v0.5 : corrected a small bug not allowing to set scaling max as freq in 3 tunables

Anyway this is just for a quick release, a new version is in the making, so this will be dropped anyway...

Version number was missing "b"...

Fixed freezes/reboots when switching from zzmoove to another governor on-the-fly (by ZaneZam)
cpufreq: zzmoove governor v0.5.1b-beta6

Rewrite of scaling, using logic and system frequency table instead of a lookup table

Reverted, this was a double fix, and certain deadlock (mutex) ... sorry for this !
cpufreq: zzmoove governor v0.5.1b (by ZaneZam)

Changelog:

- highly optimised scaling logic (thx and credits to Yank555)
- simplified some tuneables by using already available stuff instead of using redundant code (thx Yank555)
- reduced/optimised hotplug logic and preperation for automatic detection of available cores
  (maybe this fixes also the scaling/core stuck problems)
- finally fixed the freezing issue on governor stop!
