Subject: drm/tilcdc: tilcdc_tfp410: make of_device_ids const.
Git-commit: cafdee68fbd87ff8c2730117d65f095c33b506fe
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

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