Indeed the 2 'const' don't have the same meaning so the original code
may be correct but with an array like cqspi_dt_ids[] we can't write
"cqspi_dt_ids = (const struct of_device_id *)<right value>;" anyway.
So I think the 2nd 'const' is useless here then if this patch removes a
warning, let's apply it, right?
