[media] media: platform: soc_camera_platform : constify v4l2_subdev_* structures
v4l2_subdev_{core/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.
Done using Coccinelle:(One of the scripts)
