ELF related fields elf_headers, elf_headers_sz, and elf_headers_mem
have been moved from 'struct kimage_arch' to 'struct kimage' as
elf_headers, elf_headers_sz, and elf_load_addr respectively.

Use the ELF fields defined in 'struct kimage'.

Fixes: 33488dc4d61f ("of: Add a common kexec FDT setup function")

This Fixes tag should be removed. It is referencing a patch from the
future (later in the series), and the commit id is meaningless.
