mach-msm: mpdecision: add load based decision making

This now works like the mpdecision binary from QCOM.
CPU hotplugging/unplugging based on system load.

A sysfs interface will be built in with a later commit.

mach-msm: mpdecision: restructure locks, add delay

The new delay allows the CPU to come up before any other action is taken.
This prevents fast plugging and also ensures the CPU hotplug process
is really done, before trying to unplug it again (or plug it).

The new locks are more efficient, and only used if necessary.

mach-msm: mpdecision: pause if CPU is unplugged outside of mpdecision

This fixes cpu wars if something else tries to control the cpus.

just isn't accurate anymore.
