It's been replaced with support in the bootm command for passing the .dtb

New boot sequence:
1) load kernel into memory (or flash)
2) load initrd into memory (optional)
3) load .dtb into memory (optional)
4) bootm <kenreladdr> [initrdaddr] [dtbaddr]

If a dtbaddr is provided; then the dtb is passed to the kernel.  If it
is not; then old style booting is used instead.
If you don't have an initrd, but do have a .dtb; pass '-' as the initrdarrd.
