[PATCH 4.9 60/92] Input: xpad - constify usb_device_id

[ Upstream commit 94aef061c796d3d47f1a2eed41e651ffaaade402 ]

usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by <linux/usb.h> work with
const usb_device_id. So mark the non-const structs as const.
