auto_hotplug.c: just hardcode the value for onlining all the cpus.

auto_hotplug.c: only call CPU offlining if avg_running < disable_load/2, online_cpus > 1 and if BOOSTPULSE is up. Decreased the BOOSTPULSE unpause timing to 2 seconds from 5. Add BOOSTPULSE function call to the touch driver so that the device keeps 2 cores up when the user is interacting with the device.
