The EFI capsule authentication logic in u-boot expects the public key in the form of an EFI Signature List(ESL) to be provided as part of the platform's dtb. Currently, the embedding of the ESL file into the dtb needs to be done manually. Add a target for generating a dtsi file which contains the signature node with the ESL file included as a property under the signature node. Include the dtsi file in the dtb. This brings the embedding of the ESL in the dtb into the U-Boot build flow. The path to the ESL file is specified through the CONFIG_EFI_CAPSULE_ESL_FILE symbol.
