usb: gadget: constify usb_gadget_ops structures

Declare usb_gadget_ops structures as const as they are only stored in
the ops field of a usb_gadget structure. This field is of type const, so
usb_gadget_ops structures having this property can be declared const
too.
Done using Coccinelle:

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

@ok1@
identifier r1.i;
position p;
struct fotg210_udc fotg210;
@@
fotg210.gadget.ops=&i@p

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

i@p

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