[PATCH v18 02/11] arm64: Rename kexec elf_headers_mem to elf_load_addr

[Lakshmi Ramasubramanian]

The architecture specific field, elf_headers_mem in struct kimage_arch,
that holds the address of the buffer in memory for ELF core header for
arm64 has a different name than the one used for powerpc.  This makes
it hard to have a common code for setting up the device tree for
kexec system call.

Rename elf_headers_mem to elf_load_addr to align with powerpc name so
common code can use it.
