[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  work with const
of_device_ids. So mark the non-const structs as const.

File size before:
   textdata bss dec hex filename
   20012168  4842171079 drivers/crypto/n2_core.o

File size after constify dummy_tlb_ops.:
   textdata bss dec hex filename
   3601 536  4841851059 drivers/crypto/n2_core.o
