I'm fine with this. We may re-add an entry when BP is used or if someone
reports there's a flash with this ID that doesn't support SFDP, which
has a reasonable amount of probability for macronix flashes, but I'm ok
taking the risk and fixing it afterwards if reported.

Waiting a bit more to get Michael's and Pratyush's opinions on this too.
