cpufreq: zzmoove governor v0.7 (aka. tamed beast)

 * Version 0.7 - slow down (in cooperation with Yank555)
 *
 *	- reindroduced the "old way" of hotplugging and scaling in form of the "Legacy Mode" (macros for enabling/disabling this done by Yank555, thx!)
 *	  NOTE: this mode can only handle 4 cores and a scaling max frequency up to 1800mhz.
 *	- added hotplug idle threshold for a balanced load at CPU idle to reduce possible higher idle temperatures when running on just one core.
 *        (inspired by JustArchi's observations, thx!)
 *	- added hotplug block cycles to reduce possible hotplugging overhead (credits to ktoonsez)
 *	- added possibility to disable hotplugging only at suspend (inspired by a request of STAticKY, thx for the idea)
 *	- introduced hotplug frequency thresholds (credits to Yank555)
 *	- hotplug tuneables handling optimized (credits to Yank555)
 *	- added version information tuneable (credits to Yank555)
 *
 *	  for this functions following new tuneables were indroduced:
 *
 *	  legacy_mode			-> for switching to the "old" method of scaling/hotplugging. possible values 0 to disable,
 *					   any values above 0 to enable (default is 0)
 *	  				   NOTE: the legacy mode has to be enabled by uncommenting the macro ENABLE_LEGACY_MODE below!
 *	  hotplug_idle_threshold	-> amount of load under which hotplugging should be disabled at idle times (respectively at scaling minimum).
 *					   possible values 0 disable, from 1 to 100 (default is 0)
 *	  hotplug_block_cycles		-> slow down hotplugging by waiting a given amount of cycles before plugging.
 *					   possible values 0 disbale, any values above 0 (default is 0)
 *	  disable_hotplug_sleep		-> same as disable_hotplug but will only take effect at suspend.
 *					   possible values 0 disable, any values above 0 to enable (default is 0)
 *	  up_threshold_hotplug_freq1	-> hotplug up frequency threshold for core1.
 *					   possible values 0 disable and range from over down_threshold_hotplug_freq1 to max scaling freqency (default is 0)
 *	  up_threshold_hotplug_freq2	-> hotplug up frequency threshold for core2.
 *					   possible values 0 disable and range from over down_threshold_hotplug_freq2 to max scaling freqency (default is 0)
 *	  up_threshold_hotplug_freq3	-> hotplug up frequency threshold for core3.
 *					   possible values 0 disable and range from over down_threshold_hotplug_freq3 to max scaling freqency (default is 0)
 *	  down_threshold_hotplug_freq1	-> hotplug down frequency threshold for core1.
 *					   possible values 0 disable and range from min saling to under up_threshold_hotplug_freq1 freqency (default is 0)
 *	  down_threshold_hotplug_freq2	-> hotplug down frequency threshold for core2.
 *					   possible values 0 disable and range from min saling to under up_threshold_hotplug_freq2 freqency (default is 0)
 *	  down_threshold_hotplug_freq3	-> hotplug down frequency threshold for core3.
 *					   possible values 0 disable and range from min saling to under up_threshold_hotplug_freq3 freqency (default is 0)
 *	  version			-> show the version of zzmoove governor
Touch Wake : bump to v1.1a (Yank555.lu)

- fixed touch wake disbaled as soon as proxy sensor was enabled, no matter if proximity was detected or not (my derp, introduced in 1.1)
- fixed proximity state change detection (is in cm36651.c, not ssp_input.c, which is not compiled for i9300)
- removed "off hook" detection, it was relying on a constant (PSTN_ON_HOOK, defined in telephony.h), so made no sense to keep it
