Subject: [PATCH net-next 1/3] dt-bindings: net: mscc-miim: add lan966x compatible

The MDIO controller has support to release the internal PHYs from reset
by specifying a second memory resource. This is different between the
currently supported SparX-5 and the LAN966x. Add a new compatible to
distiguish between these two.
