It might be better to call the existing at91_nand_enable() and
at91_nand_disable() functions.
ie,
        if (ctrl & NAND_CTRL_CHANGE) {
                if (ctrl & NAND_NCE)
                        at91_nand_enable(host)
                else
                        at91_nand_disable(host);
        }
