Three kind of interface modes supported by qca8084. PHY_INTERFACE_MODE_10G_QXGMII, PHY_INTERFACE_MODE_2500BASEX and PHY_INTERFACE_MODE_SGMII. The PCS(serdes) and clock are also needed to be configured to bringup qca8084 PHY, which will be added in the pcs driver. The additional CDT configurations used for qca8084.
