There is no reason to restrict access to this attribute, as it merely
reports whether crash elfcorehdr is automatically updated on CPU hot
plug/unplug and/or online/offline events.
Note that since commit 79365026f8694 ("crash: add a new kexec flag for
hotplug support"), this maps to the same flag which is world-accessible
through /sys/devices/system/memory/crash_hotplug.
