[utopic SRU] (upstream) xgene-enet: add SGMII based 1GbE support for the second port

[Craig Magina]

This patch set enables the second SGMII port on the xgene-1 mustang board.
The patches were backported by APM and tested by them as well as myself. This is the same patch set used for trusty, minus one patch that utopic already had.
