sfp: add SFP module support
Add support for SFP hotpluggable modules via sfp-bus and phylink. This supports both copper and optical SFP modules, which require different Serdes modes in order to properly negotiate the link. Optical SFP modules typically require the Serdes link to be talking 1000BaseX mode - this is the gigabit ethernet mode defined by the 802.3 standard. Copper SFP modules typically integrate a PHY in the module to convert from Serdes to copper, and the PHY will be configured by the vendor to either present a 1000BaseX Serdes link (for fixed 1000BaseT) or a SGMII Serdes link. However, this is vendor defined, so we instead detect the PHY, switch the link to SGMII mode, and use traditional PHY based negotiation.
