fdt: Build an SPL binary without device tree

Browse source 
At present u-boot-spl.bin holds the plain SPL binary without the device
tree. This is somewhat annoying since you need either u-boot-spl.bin or
u-boot-spl-dtb.bin depending on whether device tree is used.

Adjust the build such that u-boot-spl.bin includes a device tree
(if enabled), and the plain binary is in u-boot-spl-nodtb.bin. For now
u-boot-spl-dtb.bin remains the same.
