Subject: [media] s5p-mfc: v4l2 controls setup routine moved to initialization 
code
Author:  Andrzej Hajda <a.ha...@samsung.com>
Date:    Tue May 28 03:26:15 2013 -0300

Callback .start_streaming is called once for every queue,
so v4l2_ctrl_handler_setup was called twice during stream start.
Moving v4l2_ctrl_handler_setup to context initialization
reduces numbers of calls and seems to be more consistent with API.
