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
