Curiously enough, mdio_device_create() only calls device_initialize().
It's mdio_device_register() that calls device_add(). So after this
patch, we cannot call lynx_pcs_create() without calling
mdio_device_register().

OK, so presumably we need to call mdio_device_register after mdio_device_create.
I suppose I should have caught this because patch 5 does exactly this.

And that's only to not crash during boot, mind you. Networking is broken
at this stage. I'll proceed to patch 5 to see what happens next.
