Subject: [PATCH] crypto: sahara : 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:
   text	   data	    bss	    dec	    hex	filename
  10367	   2128	      8	  12503	   30d7	drivers/crypto/sahara.o
