net: ethernet: ti: cpsw: add support for port interface mode selection phy
Add support for port interface mode selection phy (phy-gmii-sel): - try to request interface mode selection phy from Port DT node and fail silently if not defined and old CONFIG_TI_CPSW_PHY_SEL driver enabled. - use new phy if requested successfully.
