Well, that why I suggested to merge the two defconfig. But I'm fine having two
defconfig for different purpose.

I would like to continue enabling features in the qemu_aarch64_virt_defconfig
and some of them require ACPI support. That is why I borrowed the post-image
script, grub defconfig from aarch64_efi_defconfig and packaged the edk2-bin.

If we start enabling qemu runtime testing for other defconfig that the one named
qemu_* we could continue (for example) test the nitrogen6x_defconfig with
qemu-system-arm -M sabrelite. This can be interesting :)

For now, I would like to focus on qemu_* defconfigs.

Best regards,
Romain
