macintosh/rack-meter: 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 before:
   text    data     bss     dec     hex filename
    407     576       0     983     3d7 drivers/macintosh/rack-meter.o

File size after constify rackmeter_match.
   text    data     bss     dec     hex filename
    807     176       0     983     3d7 drivers/macintosh/rack-meter.o
