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.

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.

msm_mpdecision: add input event boost [read more]

This adds an input event boost to mpdecision.
It will basically boost the min freq of all cpus to predefined values if an
input event is detected.
Devices that qualify as boosters must fullfill one of these conditions:
- contain touch in their name
- contain keyboard in their name
This also boosts cpus independently from each other. Meaning:
If a cpu is hotplugged after the boost of another cpu was initiated the next
boost pulse will boost that cpu too.

Sysfs interface underway.
