TI phy requires a reset before PHY address detection to make sure correct strapping via MIO is detected. Facilitate the same using ethernet-phy-id compatible string. GPIO reset entry will be added in a separate commit. This support is present in RevA but needs to be extended to RevB/1.0/1.1 versions which are built on top.
