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.
