These are set in the barebox class rather in the corresponding machines (where they would belong otherwise) to keep the impact of barebox to oe-core minimal for now. "multi_v7_defconfig" is used for qemuarm since this is the default barebox armv7 config that just enables all supported platforms. "multi_v8_defconfig" is used for qemuarm64 sine this is the default barebox armv8 config that just enables all supported platforms. "efi_defconfig" is used for qemux86-64 which is the primary platform where barebox will not be the first stage bootloader but an EFI payload. Since these changes make barebox a provider for virtual/bootloader, explicitly default to u-boot in the corresponding MACHINE configs to not unnecessarily surprise users.
