Without the prefix, "same-as-spl" in `u-boot,spl-boot-order` will not work as expected. When board_boot_order() `spl-boot-order.c` meets "same-as-spl", it gets the conf by looking the boot_devices table by boot source, and parse the node by the conf with: node = fdt_path_offset(blob, conf); which will failed without the "/" indicating the path. Currently only entries of boot_devices in rk3399 have the "/" prefix. Therefore add the missing ones in other boards.
