esoc: Add err_fatal signal status to clink_ops
Auto_boot esoc devices can boot and crash before
esoc driver comes up. But there is no way for the
user space code to know that it has crashed by looking
at status line alone. Hence, create a new ioctl entry
to export status of err_fatal line to user space.
