net: ieee802154: constify ieee802154_ops structures

Declare the structure ieee802154_ops as const as it is only passed as an
argument to the function  ieee802154_alloc_hw. This argument is of type
const struct ieee802154_ops *, so ieee80254_ops structures having this
property can be declared as const.
Done using Coccinelle:

@r1 disable optional_qualifier @
identifier i;
position p;
@@
static struct ieee802154_ops i@p = {...};

@ok1@
identifier r1.i;
position p;
expression e1;

ieee802154_alloc_hw(e1,&i@p)

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