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:

File size after constify cdns_wdt_of_match:
   text    data     bss     dec     hex filename
   2378     196       4    2578     a12 drivers/watchdog/cadence_wdt.o
