Subject: [PATCH] mtd: increase max page/OOB size to support 16K pagesize NAND.

The Toshiba's TC58TEG5DCJTA pagesize is 16K, oob size is 1280 bytes.
So increase the NAND_MAX_OOBSIZE and NAND_MAX_PAGESIZE.

Huh? I hope you're not intentionally forging Signed-off-by lines...
Presumably the follow-up (re)send is because this one was an accident?
