From: Claudiu Manoil <claudiu.manoil@nxp.com> Link the switch PHY nodes to the central MDIO controller PCIe endpoint node on LS1028A (implemented as PF3) so that PHYs are accessible via MDIO. Enable SGMII AN on the Felix PCS by telling PHYLINK that the VSC8514 quad PHY is capable of in-band-status. The PHYs are used in poll mode due to an issue with the interrupt line on current revisions of the LS1028A-RDB board.
