[PATCH] crypto: n2: make of_device_ids const

[Arvind Yadav]

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
   2001	   2168	     48	   4217	   1079	drivers/crypto/n2_core.o

File size after constify dummy_tlb_ops.:
   text	   data	    bss	    dec	    hex	filename
   3601	    536	     48	   4185	   1059	drivers/crypto/n2_core.o
