drm: sti: sti_dvo: make of_device_ids const.

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 after constify dvo_of_match:

   4638	    248	      0	   4886	   1316	drivers/gpu/drm/sti/sti_dvo.o
