Subject: [PATCH v2 net-next 2/2] r8169: support RTL8168G

Support the new chip RTL8168G.
For RTL8111G, the settings of phy and firmware are replaced with ocp functions.
The r8168g_mdio_{write / read} would redirect the relative settings to suitable
opc functions. However, a global variable ocp_base is needed to calculate the
real address of ocp functions. rtl_writephy(tp, 0x1f, xxxx) means the changing
of ocp_base.
