Version 0.9 beta4

Changelog:

- removed 'freq_step' functionality as it never had any function in this governor. it was a left over from mialwes 'smoove' governor and also
  had no function in his governor back then. so yeah all the 'feelings' about it's influence were placebo :)
- introduced 'proportional scaling' for more 'connectivity' to current load, this should give more 'balanced' frequencies
  in general. when enabled all targeted frequencies in scaling logic will be compared with the ones from system table method and at the end
  the lowest of them both will be used. so all used scaling frequencies will be 'tentential' lower in both directions
- added support for exynos4 CPU temperature reading (patches available in zzmoove repositories: https://github.com/zanezam)
  this must be enabled via 'CONFIG_EXYNOS4_EXPORT_TEMP=y' in the config of a kernel which has exynos4 CPU temperature export implementation
  included. the default temp polling interval is 1000 ms and can be set with DEF_TMU_READ_DELAY. however the TMU driver has it's own polling
  interval which is 10 seconds, so leaving it at the default value of 1 second is recommended temperature reading will only be enabled if the
  tuneable 'scaling_block_temp' is set and will be disabled whenever early suspend is entered
- if exynos4 CPU temperature reading is enabled in the code use current CPU temperature in scaling block functionality to be able to 'hold' the cpu
  temperatue to the given one in 'scaling_block_temp'. this function is used in combination with the already existent tuneable 'scaling_block_freq'
  so u have to set both to enable it. the possible temperature range is 30°C to 80°C (lower temps are making no sense and higher temps would reach
  into exynos4 TMU driver trottling range)
- if exynos4 CPU temperature reading is enabled added current CPU temperature to debug info tuneable
- added auto adjustment of all available frequency thresholds when scaling max limit has changed
- improved sampling rate idle switching by making it scaling thresholds independent
- again some code style and comment changes/fixes

profile header file (Version 0.2 beta3):

- added scaling block temperature tuneable to all profiles if CONFIG_EXYNOS4_EXPORT_TEMP is defined
- use CPU temperature treshold of 65°C instead of 15 scaling block cycles in game profile if
  CONFIG_EXYNOS4_EXPORT_TEMP is defined
- added proportional frequency tuneable to all profiles
- added auto adjust freq thresholds to all profiles (disabled by default)
- enabled scaling proportional in ybat, ybatext, zzbat, zzbatp, zzmod and zzgame profile
- enabled scaling fast down over 1200MHz and resposiveness over 400Mhz with up threshold of 20
  in ybat, ybatext, zzbat, zzbatp, and zzmod profile
- added core macros to exclude not used code like it is in governor
- removed freq_step tuneable from all profiles
