Subject: [PATCH v2 net-next 08/10] dt-bindings: net: pcs: mediatek,sgmiisys: deprecate "mediatek,pnswap"

Reference the common PHY properties, and update the example to use them.
Note that a PCS subnode exists, and it seems a better container of the
polarity description than the SGMIISYS node that hosts "mediatek,pnswap".
So use that.
