intelli_plug: use rq_stats to help detect artificial or constant loads

benchmarks often create fake / artificial loads at a constant rate.  These
type of loads are not detected corectly by run average algorithms. Use
the run queue stats to help detect these cases and bring up the cores in
correspondence.

intelli_plug: use mp_decision() algorithm for core 3 and 4

intelli_plug: use mp_decision to reduce online persistence count for cores

this should bring down the cores faster when run queue is low
also optimized code a bit using local vars

intelli_plug: disable by default

let the user enable via sysfs so it won't clash with mpdecision which is
enabled by default for qualcomm phones

intelli_plug: add dynamic load sampling rate logic

Add dynamic sampling logic based on load. If load is high and required more
than 2 cores, increase the sampling rate for a duration of 3 seconds to help
manage the load better during this time.  Once duration expires, revert back
to lazier sampling rate for better batter performance.

global workqueue is busy and cleaned up some logic issues.

intelli_plug: code review clean up

set def sampling rate to something sane rather than zero (instantaneous
rescheduling is not good if intelli_plug is disabled)

make touch input more generic rather than tied to a touchscreen driver

remove unused code

intelli_plug : move to its own directory. It's been cross platform for a while

intelli_plug driver has been working on OMAP44xx, TEGRA 3, Exynos and
MSM Krait/Cortex multi-core SOCs.  So it doesn't make sense to patch on a per
SOC basis, move it to its own ARM platform independent folder so patches can
apply to all supported ARM platforms

kernel/power/powersuspend: new PM kernel driver for Android w/o early_suspend v1.5 (Yank555.lu)

- fix hybrid-kernel mode cannot be set through sysfs

kernel/power/powersuspend: new PM kernel driver for Android w/o early_suspend v1.4 (Yank555.lu)

- add hybrid-kernel mode (autosleep and panel, first wins)
- default to hybrid-kernel mode
- harmonize debug message with my other stuff
- include all 3 modes as default, so it's only commenting out to change

- add an alternative hook for screen on / off detection in the display panel driver
(sleeps ~0.1s sooner, wakes up ~1s later then autosleep)
