[media] exynos4-is: constify v4l2_subdev_* structures
v4l2_subdev_{core/pad/video}_ops structures are stored in the fields of the v4l2_subdev_ops structure which are of type const. Also, v4l2_subdev_ops structure is passed to a function having its argument of type const. As these structures are never modified, so declare them as const.
