mtd/nand/vf610_nfc: Disable subpage writes
This patch disables subpage writes for vf610_nfc nand driver. This is required, as without this fix, writing unaligned u-boot images with DFU results in a hang. Trying to write unalgined binary images also results in a hang, without disabling subpage writes. Patch has been tested on a Colibri VF61 module.
