Subject: [net-next PATCH v2 03/10] net: netcp: ethss: make call to gbe_sgmii_config() conditional

As a preparatory patch to add support for 2u cpsw hardware found on
K2G SoC, make call to gbe_sgmii_config() conditional. This is required
since 2u uses RGMII interface instead of SGMII and to allow for driver
re-use.
