msm8976-common: camera: Store user pointer and pass it when needed

The new camera interface calls set_callbacks with a pointer
to it's internal CameraDevice and expects following calls to
the callbacks to use that pointer.

Store the pointer in the camera wraper and intercept the
callbacks calls to pass it along.
