Bhumika Goyal 977ac78950 usb: gadget: udc: constify usb_ep_ops structures 
Declare usb_ep_ops structures as const as they are only stored in the
ops field of an usb_ep structure. This field is of type const, so
usb_ep_ops structures having this property can be made const too.
Done using Coccinelle( A smaller version of the script)
