Subject: [PATCH] crypto: caam: 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 caam_jr_match:
   text	   data	    bss	    dec	    hex	filename
   2976	    192	    128	   3296	    ce0	drivers/crypto/caam/jr.o
