At present the AE350 SPL defconfig is using OF_PRIOR_STAGE. The intention was to use gdb to load device tree before running U-Boot SPL/proper from RAM. When we switch to OF_SEPARATE we will have to use our own DT but without "u-boot,dm-spl" in several essential nodes, SPL does not boot.
Let's add all the required "u-boot,dm-spl" for SPL config.
