[RFC] mtd/nand: modify NAND_CHIPOPTIONS_MSK

[Jan Weitzel <j.weitzel@phytec.de>]

Trying to set NAND_NO_SUBPAGE_WRITE from platform fail, because
nand_flash_detect_onfi options from struct nand_flash_dev overwrite the flag.

Removing NAND_NO_SUBPAGE_WRITE from NAND_CHIPOPTIONS_MSK fix this,
but setting it via struct nand_flash_dev table is not longer supported.
