watchdog: cadence_wdt: 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 before:

File size after constify cdns_wdt_of_match:

   2378	    196	      4	   2578	    a12	drivers/watchdog/cadence_wdt.o
