MSM and INTELLI HOPLUGS: Tune the settings and fix fast lane

*I have found that stats.cur_avg_load on real high load show 214 load
and my fast lane was set to 99. so on any half way load, all cores jumped!
I have replaced stats.cur_max_load with stats.cur_avg_load in fast lane
and now it's working as should! no more cores jump on simple finger swipe.

*I ahve reduced the MIN freq for fast lane to freq that existing when CPU
is overheated and limitted to 1.7/1.9GHZ so fast lane can still work.
and reduce hotplug calcs on hih load. just keep the cores ON baby.

*Reduced HotPlug start from 20sec to 5. on hotplug start all cores
are ON and stuck on some freq till work is starting... looks bad.
now 5 sec all motor running.

*Reduced BOOST core delay, there is no reason to hold cores 2500msec
without any need. 500msec is more than needed.
will save power like that.
