mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver
commit bf7a01bf7987b63b121d572b240c132ec44129c4 upstream. The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.
