bricked_hotplug: Initial adaptation

* Renamed from msm_mpdecision to bricked_hotplug in
  order to avoid confusion with stock mpdecision binary.
* Removed unnecessary header file.
* Removed boost framework. Hotplug driver should not
  boost frequency.
* Removed faulty "enabled" switch.
* Added proper "bricked_enabled" switch.
* Added proper logic to disable interference when
  switched off!
* Disabled by default.
* Experimental and lots rework needed to add tunables
  equivalent to that in our MSM and Intelli Hotplug.
