Staging: media: radio-bcm2048: constify v4l2_ioctl_ops structure

Declare the structure v4l2_ioctl_ops as const as it is only stored in
the ioctl_ops field of video_device structure. As this field is of type
const struct v4l2_ioctl_ops *, so v4l2_ioctl_ops structures having this
property can also be made const.
Done using coccinelle:

@r1 disable optional_qualifier @
identifier i;
position p;

static struct v4l2_ioctl_ops i@p = {...};

@ok1@
identifier r1.i;
position p;
struct video_device s;
