[PATCH v2 08/14] ppc, crash: enforce KEXEC and KEXEC_FILE to select CRASH_DUMP

[Baoquan He <bhe@redhat.com>]

In PowerPC, the crash dumping and kexec reboot share code in
arch_kexec_locate_mem_hole(), in which struct crash_mem is used.

Here enfoce enforce KEXEC and KEXEC_FILE to select CRASH_DUMP for now.
