As we are careful not to register external interfaces before the
internals are brought up, we are not dependent upon a synchronous
probing and can allow ourselves to be probed from a secondary thread
during system bootup. We already do relegate some configuration to
asynchronous tasks (such as setting up the fbdev), now do the entire
probe.
