From: Sean Wang <sean.wang@mediatek.com> adds PHY-mode "trgmii" as an extension for the operation mode of the PHY interface for PHY_INTERFACE_MODE_TRGMII. and adds a variable trgmii inside mtk_mac as the indication to make the difference between the MAC connected to internal switch or connected to external PHY by the given configuration on the board and then to perform the corresponding setup on TRGMII hardware module.
