PATCH 1/1 mtd: spinand: winbond: Add support for W25N01GV
W25N01GV is a single die version of the already supported W25M02GV with half the capacity. Everything else is the same so introduce support for W25N01GV.

Hi Robert,
Please Cc the NAND mantainers when you send a NAND related patch (in case you don't know about it already, scripts/get_maintainer.pl should help you find who to Cc).
