[media] media: i2c: m5mols: m5mols_core: constify v4l2_subdev_pad_ops structures 

v4l2_subdev_pad_ops structures are stored in the pad field
of the v4l2_subdev_ops structure and this field is of type const.
As the v4l2_subdev_pad_ops structures are never modified, they can be
declared as const.
Done using Coccinelle:

@r1 disable optional_qualifier @
identifier i;
position p;
@@
static struct v4l2_subdev_pad_ops i@p = {...};

@ok1@
identifier r1.i;
position p;
struct v4l2_subdev_ops obj;
@@
obj.pad=&i@p;

@bad@
position p!={r1.p,ok1.p};
identifier r1.i;

i@p

@depends on !bad disable optional_qualifier@
identifier r1.i;
