cpufreq: ondemand: add input_boost interface

Currently Ondemand governor handles any input event
like touch by scaling the CPU frequency to maximum
available on the target.

This change adds a new sysfs interface "input_boost"
whereby the CPU will scale to this frequency on input events.
The value of this sysfs is user defined so input events
can now be handled by scaling the CPU to lower frequencies
than target max.
