Subject: drm: sti: sti_hqvdp: make of_device_ids const.
Git-commit: 4c952eaba7789e0b1f2c146e839fd82c5a290241
Patch-mainline: v4.14-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.

File size before:
   text	   data	    bss	    dec	    hex	filename
  15845	    640	      0	  16485	   4065	drivers/gpu/drm/sti/sti_hqvdp.o

File size after constify hqvdp_of_match:
   text	   data	    bss	    dec	    hex	filename
  16229	    224	      0	  16453	   4045	drivers/gpu/drm/sti/sti_hqvdp.o
