Add this file, generated from qemu, so there is a reference devicetree in the U-Boot tree.

Note that the dtb you get from QEMU is only guaranteed to work if:
- you run it on the exact same QEMU version you generated it with
- you pass QEMU the exact same command line arguments you used when you generated it
Yes, I certainly understand that. In general this is not safe, but in practice it works well enough for development and CI. I am able to use QEMU versions that differ by two years, partly because I am not trying to do anything clever.
I have sent a patch to add an indication of where the devicetree came from, to help with visibility on this.
