ELF related fields elf_headers, elf_headers_sz, and elf_load_addr are defined in architecture specific 'struct kimage_arch' for x86, powerpc, and arm64. The name of these fields are different in these architectures that makes it hard to have a common code for setting up the device tree for kexec system call. Move the ELF fields to 'struct kimage' defined in include/linux/kexec.h so common code can use it.
