mtd: nand: mtk: add ->setup_data_interface() hook
Currently, we use the fixed ACC timing 0x10804211. This is not the best setting for each case. Actually, MTK NAND controller can adapt ACC timings dynamically according to nfi clock frequence. Implement the ->setup_data_interface() hook to optimize driver performance. Signed-off-by: NXiaolei Li <xiaolei.li@mediatek.com> Signed-off-by: NBoris Brezillon <boris.brezillon@free-electrons.com>
