Document support for Airoha Ethernet PCS for AN7581 SoC. Airoha AN7581 SoC expose multiple Physical Coding Sublayer (PCS) for the various Serdes port supporting different Media Independent Interface (10BASE-R, USXGMII, 2500BASE-X, 1000BASE-X, SGMII). This follow the new PCS provider with the use of #pcs-cells property.
