Staging: emxx_udc: constify usb_ep_ops structure
Declare the structure usb_ep_ops as constant as it is only stored in the
ops field of a usb_ep structure which is a field of a nbu2ss_ep structure.
The ops field is of type const struct usb_ep_ops *, so usb_ep_ops
structures having this property can be decalared as const.
Done using coccinelle:
@r1 disable optional_qualifier @
identifier i;
position p;

static struct usb_ep_ops i@p = {...};
@ok1@
identifier r1.i;
position p;
struct nbu2ss_ep s;
