Emmanuel Vadot 25f0326aea simplebus pnp: Do not generate pnp info is the bus status is not okay 
Generating the pnp info have the side effect to include all nodes even
if the status isn't "okay".
That means that loading the module will load but not attach as it checks
the status in the probe function.
