Remove max frequency to 800MHz when screen off
This function should remain
Fix sampling down factor selection
cpufreq: Add a boostpulse interface to ondemand

thanks to CM team
cpufreq: boostfreq: do not set to current value

dbs_tuners_ins.boostfreq should not be set upon boosting, as it
will fix the boostfreq to the current max value, despite the
fact that it can change later (via cpufreq reconfiguration)
