WIth EFI we must embed the devicetree in an ELF image so that it is loaded as part of the executable file. We want it to include the binman definition in there also, which in some cases cannot be created until the ELF (u-boot) is built. Add an option to binman to support writing the updated dtb to the ELF file u-boot.out This is useful with the EFI app, which is always packaged as an ELF file.
