The R40 SoC has a GMAC (gigabit capable Ethernet controller). Add a device node for it. The only publicly available board for this SoC uses an RGMII PHY. Add a pinmux node for it as well. Since this SoC also has an old 10/100 Mbps EMAC, which also has an MDIO bus controller, the MDIO bus for the GMAC is labeled "gmac_mdio".
