rockchip/rk3399: sdram.c: Fix msch ddrconfig register error

Fix msch ddrconfig register write error. Also make sure that the row
    number configured in msch is equal to the row number configured in the
    DDR controller.
    This would not affect systems with 4GB of memory, but is needed
    for 2GB configurations.
