ARM: dts: cm-t335: add support for network device

Browse source 
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.
