nds32: Enable two banks of SDRAM on Andes board
The original adp-ag101/adp-ag101p initialize only one bank(64MB) by default at boot time, but it is not enough for some application, so increasing to two banks(128M). Signed-off-by: Kuan-Yu Kuo <ken.kuoky@gmail.com> Cc: Macpaul Lin <macpaul@gmail.com>
