[PATCH 4/4] ARM64: configs: add multi_v8_efi_defconfig

[Ahmad Fatoum <a.fatoum@barebox.org>]

We will want to have a efi_defconfig once all necessary components are
in place, but for now let's just add a config that extends
multi_v8_defconfig with an EFI stub.

To use, get QEMU_EFI.fd (e.g., from Debian qemu-efi-aarch64) and run:

  qemu-system-aarch64 -kernel images/barebox-dt-2nd.img \
  -bios QEMU_EFI.fd -machine virt,highmem=off -cpu cortex-a57 \
  -m 1024M -nographic -serial mon:stdio -trace file=/dev/null

A labgrid YAML will follow once we can provide QEMU_EFI.fd there.
