[media] platform: constify vb2_ops structures

Check for vb2_ops structures that are only stored in the ops field of a
vb2_queue structure. That field is declared const, so vb2_ops structures
that have this property can be declared as const also.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

identifier i;

static struct vb2_ops i@p = { ... };

@ok@

e.ops = &i@p;

@bad@
position p != {r.p,ok.p};
