From: Ilya Ledvich <ilya@xxxxxxxxxxxxxx>
Add pinmux configurations for RGMII1 based CPSW Ethernet pins and
MDIO pins:
- default configuration required for module in active state,
- sleep configuration required for module in inactive state.
Add mac node with single slave device. Add nodes for davinci_mdio and
cpsw_emac0.
