[ Upstream commit 1a642ca7f38992b086101fe204a1ae3c90ed8016 ]
The older SoCs like Armada XP support a 2500BaseX mode in the datasheets referred to as DR-SGMII (Double rated SGMII) or HS-SGMII (High Speed SGMII). This is an upclocked 1000BaseX mode, thus PHY_INTERFACE_MODE_2500BASEX is the appropriate mode define for it. adding support for it merely means writing the correct magic value into the MVNETA_SERDES_CFG register.
