r8169: fix wrong PHY ID issue with RTL8168dp
As reported in [0] at least one RTL8168dp version has problems establishing a link. This chip version has an integrated RTL8211b PHY, however the chip seems to report a wrong PHY ID, resulting in a wrong PHY driver (for Generic Realtek PHY) being loaded. Work around this issue by adding a hook to r8168dp_2_mdio_read() for returning the correct PHY ID.
