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
   8908    1096     624   10628    2984 drivers/block/swim3.o

File size after constify swim3_match:
   text    data     bss     dec     hex filename
   9708     296     624   10628    2984 drivers/block/swim3.o
