fdt: Add an option to disable device tree in SPL

Some boards cannot support device tree due to lack of memory. Add an option
to allow these boards to continue to work (and even use driver model).
This is a 'negative' option since most boards are expected to support device
tree in SPL.

Some boards use device tree in U-Boot but only have 4KB of SRAM
which is not enough to support device tree. Enable this option to
allow such boards to be supported by U-Boot SPL.
