nixge: fixed-link support

Hi,

this series adds support for using nixge with fixed-link nodes, as well as an early attempt to support nixge as a subdevice of another device.

This series goes on top of: https://lkml.org/lkml/2018/8/28/1011

Patch 1: Adds of based fixed-link support, and hopefully isn't too
controversial barring grave mistakes.

Patch 2: Is an attempt at making sure that nixge works as a subdevice
of another (pci) device without a PHY. Note that same as Patch 3 the actual platform data might still change since the parent device driver is still under development. So this is more of an RFC, too.

Patch 3: Is more of an RFC at this point since the PCI parent device is
still under development, but required to run with IOMMU support. Feedback on this one would be appreciated.

Thanks for your input,

Moritz
