[PATCH 1/1] phy: Add 2.5G SGMII interface mode

[Bhaskar Upadhaya]

Add 2.5G SGMII interface mode(PHY_INTERFACE_MODE_2500SGMII)
in existing phy_interface list.As auto-negotiation is not
supported for 2.5G SGMII, we need to add a new type
PHY_INTERFACE_MODE_2500SGMII to differentiate
SGMII-1G and SGMII-2.5G with different setting for
auto-negotiation.
