' msm8960-common: CameraWrapper Updates

* Possible Memory leak updates in fixed_set_params

* Update fixup_setparams in camerawrapper to support sending rawcommand
  At times it's needed to send raw commands to the camera.  Simple change
  to make it simple to pass these directly from the fixup_sendparams method.

 CameraWrapper: rework defines

* Set the various needed flags in device trees rather than checking
  device variant in the camera wrapper's makefile.
* Move checks after CLEAR_VARS. You know, so they actually work.
  As it urns out, you can't clear variables after setting them and
  expect them to work.
* Enable some magic for newer Samsungs. Need to send a magic command
  (1508) to the camera. Nobody knows what this number actually stands
  for. Well...maybe nishu does...
