In addition MT7981 is equipped with a built-in 1000Base-T PHY which can be used with GMAC1. As many MT7981 boards make use of inverting SGMII signal polarity, add new device-tree attribute 'mediatek,pn_swap' to support them.

As this has not always been clear, both drivers developed different implementations to deal with the PCS. 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.

Make use of external PCS driver and drop the reduntant implementation in mt7530.c. As a nice side effect the SGMII registers can now also more easily be inspected for debugging via /sys/kernel/debug/regmap.
