[PATCH net 2/3] net: stmmac: socfpga: Don't check for phy to enable the SGMII adapter

[Maxime Chevallier <maxime.chevallier@bootlin.com>]

The SGMII adapter needs to be enabled for both Cisco SGMII and 1000BaseX
operations. It doesn't make sense to check for an attached phydev here,
as we simply might not have any, in particular if we're using the
1000BaseX interface mode.

So, check only for the presence of a SGMII adapter to re-enable it after
a link config.
