Since commit aed65af1cc ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the
usb_device_type, usb_if_device_type, usb_ep_device_type and
usb_port_device_type variables to be constant structures as well, placing
it into read-only memory which can not be modified at runtime.
