phylink: merge SGMII and 802.3z handling
The code handling SGMII and 802.3z is essentially the same, except that we assume 802.3z has no PHY. Re-organise the code such that these cases are merged, and exclude 802.3z mode from having a PHY attached. This results in the same link handling behaviour as before.
