[PATCH v19 03/13] powerpc: Use ELF fields defined in 'struct kimage'

[Lakshmi Ramasubramanian <nramas@linux.microsoft.com>]

ELF related fields elf_headers, elf_headers_sz, and elfcorehdr_addr
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")
