media: v4l2-subdev: Make struct v4l2_subdev_stream_config private

Browse source 
The v4l2_subdev_stream_config structure holds configuration data for a
stream. It was meant to be used internally only, but already found its
way into the ds90ub913 driver. Now that the driver has been fixed, make
the structure private to v4l2-subdev.c to avoid using it by accident.
