    mtd: fsl_ifc_nand: set NAND_NO_SUBPAGE_WRITE
    
    This controller only does ECC on full-page accesses, even though the
    ECC consists of multiple steps.  fsl_elbc_nand can get away with this
    because the ECC of an all-0xff region will be all-0xff, but this is not
    true with the ECC algorithms used by IFC.
