kernel: support for RTL8367C/S switch

From driver point of view no differance between rtl8367b and rtl8367s
if it connected through EXT2 (rgmii only).
So this trivial patch add some identification and initialization only.
SGMII/HSGMII mode for EXT1 is not implemented for the sake of patch
clairity.
