The portnr is still passed but it is padded via the usb_device struct's
portnr member. When doing a CONFIG_DM_USB=y build the only call site of
usb_setup_device() is usb_scan_device() from drivers/usb/host/usb-uclass.c
which does:

         udev->portnr = port;
         debug("Calling usb_setup_device(), portnr=%d\n", udev->portnr);
         parent_udev = device_get_uclass_id(parent) == UCLASS_USB_HUB ?
                 dev_get_parentdata(parent) : NULL;
         ret = usb_setup_device(udev, priv->desc_before_addr, parent_udev);

So portnr is always set in the usb_device strict, and that is what gets
used after this patch.
