[media] tuners: constify dvb_tuner_ops structures 

These structures are only used to copy into other structures, so declare
them as const.

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

// <smpl>
@r disable optional_qualifier@
identifier i;

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

@ok2@

memcpy(e1, &i@p, e2)
