The hotplug engine uses its own workqueue to handle IRQ requests, the
problem is that such workqueue is initialized after init_ras_IRQ, which
will cause a kernel panic if any hotplug interruption is issued in that
period of time.
This patch changes the dlpar initcall registration to make sure it will
be initialized before init_ras_IRQ.
