As the procfs export of ATAGS is not meant as a stable, general purpose
ABI it shouldn't be an independent, general configuration option.

This patch make ATAGS_PROC depend on KEXEC

          Should the atags used to boot the kernel be exported in an "atags"
          file in procfs. Useful with kexec.
