arm: qemu: Add a 64-bit SPL build

Browse Source 
Add an 64-bit SPL build for qemu so we can test the standard passage
feature.

Include a binman definition so that SPL and U-Boot are in the same image.
This requires adding a proper devicetree file for qemu_arm. It is only
used for the SPL build.

Avoid using the QEMU devicetree in U-Boot proper, so we can obtain it
from standard passage.

For now this just boots and hangs in SPL as there is no bloblist.

Series-changes: 3
- Add a build for aarch64 as well

ensures that output appears on the terminal. Use Ctrl-A X to quit.
