The dedicated PHY is using the phy_handle property to get phy device handle and the fixed-link phy is using the fixed-link property to register a fixed-link phy device. In of_phy_get_and_connect function, it help driver to get and register these PHYs handle. Therefore, here refactors this part by using of_phy_get_and_connect.
