Subject: [PATCH v2 1/3] phy: ti: gmii-sel: Add support for SGMII mode
Add support to configure the CPSW MAC's PHY in SGMII mode if the SoC
supports it. The extra_modes member of the phy_gmii_sel_soc_data struct
corresponding to the SoC is used to determine whether or not the SoC
supports SGMII mode.
