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.

I already sent the pull request to Thomas, so this one will have to
wait. In general, it'd be better if you sent these fixes as a series for
a given subsystem rather than one or two patches every other day.

Thanks,
