There's also a PCIe bus available on the SoC. It is not yet supported,
but we'll eventually need the entire PCI subsystem, which is not that huge as it may seem, btw.

Besides, the internal PCI driver has already been submitted to the PCI mailing list
and applied to Bjorn's tree.

I don't see how treating the PCI devices as platform devices is better than
adjusting the initialization order of the USB phy.
