Title:
  [SRU] xgene-enet: add SGMII based 1GbE support for the second port

Bug description:
  [Impact]
  APM's Mustang boards have a second SGMII based 1GbE interface that is currently unsupported by Ubuntu.

  [Test Case]
  Verify that the previously non-working SGMII based 1GbE interface now works.

  [Regression Risk]
  Since the changes touch the driver that supports the existing GbE and first SGMII support, it is possible that that support has become impacted. The changes also impact drivers/of/of_net.c, which could impact other users of the interface.
