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.
BUG=None
