From: Mugunthan V N <mugunthanvnm@xxxxxx>
Adding CPSW phy-id, CPSW and MDIO pinmux configuration for active
and sleep states and enable them in board evm dts file.
Signed-off-by: Mugunthan V N <mugunthanvnm@xxxxxx>
[Resolved merge conflict and rebased on 3.8 kernel.
Update the pinmux configuration for CPSW and MDIO by removing the
macro definitons to match the 3.8 implementation.]
