It is preferable to do the test on spi-nor/next

You'll need a way to differentiate between W25Q16JV-IQ/JQ and W25Q16JV-IM/JM.
And I would prefer to have the new entries ordered alphabetically as much as
possible. This one should fit just before w25q20cl. Manufacturers are naming
flashes based on a product identification system. The flashes are presented in
alphabetical order, we should do the same.
