Subject: [PATCH] sfp: provide netdev sfp_bus and use for start/stop

Add a netdev sfp_bus pointer for propagating the phylink start/stop
actions to the SFP cage: the SFP cage may not be directly connected to
phylink, but may be the other side of a fixed PHY, and SFP needs to
know when the netdev is brought up or taken down.
