OnDemand tweaks. Interactive is still the default governor, but this
should make OnDemand more usable.
cpufreq: interactive and ondemand changes
minor changes to ondemand
Revert "minor changes to ondemand"

Interactive: set input boost freq to lp max of 620Mhz

cpufreq: interactive: set floor freq as input boost freq as well
instead of hispeed freq
cpufreq: interactive: remove exponential boost policy code and params
cpufreq: interactive: limit initial speed bump to input boost freq as well
When go hispeed load is met, and current target freq is less than both hispeed freq and input boost freq, go to the lesser of the two freqs.
If the hispeed load is met and the current target freq is less than hispeed freq but greater than or equal to input boost freq, boost to hispeed freq.
cpufreq: interactive: run at fraction of hispeed_freq when load is low
cpufreq: interactive: if hispeed freq > input freq, run at fraction of average when load is low
cpufreq: interactive: set hispeed freq to 1.1Ghz
cpufreq: interactive: set go hispeed load to 80
Revert "cpufreq: interactive: limit initial speed bump to input boost freq as well"

This reverts commit d299f1b45e143b0a6071a40a50c4a26a286f9e78.
