net: pcs: add driver for MediaTek SGMII PCS
The SGMII core found in several MediaTek SoCs is identical to what can also be found in MediaTek's MT7531 Ethernet switch IC. As this has not always been clear, both drivers developed different implementations to deal with the PCS. Recently Alexander Couzens pointed out this fact which lead to the development of this shared driver. Add a dedicated driver, mostly by copying the code now found in the Ethernet driver. The now redundant code will be removed by a follow-up commit.
