mach-msm: Add msm_mpdecision

This currently only does the following thing:
Screen on -> CPU1 online
Screen off -> CPU1 offline

More to come.

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.
default delay: 10000ms

msm_mpdecision: use own workqueues

This will alter mpdecision to alloc it's own wq rather than using
the predefined queue which is a shared resource.

The WQ is not bound to the issuer CPU (=high-priority), has a
rescue worker task and is freezable.
Also destroy the workqueue on exit, and rename msm_mpdec to
msm_mpdec_init.
