Included the basic size info for NAND chips with ID of 0xAD or
0xD7. The first can be found in Hynix HY27SF161G2M, while the
second can be found in Micron MT29F64G08 and the Samsung K9LBG08U0D
(among others). Also, some 64 Gbit (or larger) chips identify as
0xD7 because they contain multiple smaller 32 Gbit chips. I
assume it's safe to classify these under the 32 Gbit listing.

I an not sure this is safe, but I guess if someone needs to support
those NANDs, they'll have to do that properly.

Pushed to l2-mtd-2.6.git / master.
