msm8660: Change owner of /dev/ion to media

 * This is required to allow mediaserver to open /dev/ion directly. The
   current iteration of camera drivers used on this hardware does it's
   own buffer management and thus needs to open the raw device or
   mediaserver will crash when attempting to receive the JPEG image.
