The only w25q128 variant I could find with 0xef4018 as ID is
w25q128fv, which supports both dual and quad read mode.
Add these two flags in chip info.

Hi,
This duplicates the first patch in
https://patchwork.ozlabs.org/project/linux-mtd/list/?series=139324. Can I have
your Reviewed-by tag on those instead?
Thanks,
ta
