boards/t1040qds: Adds ethernet support for T1040
Enable entherent for T1040QDS. It enables FM1@DTSEC3, FM1@DTSEC4, FM1@DTSEC5 Define MDIO related configs Added eth.c file Update t1040.c to support RGMII and SGMII Update t1040qds.c to support ethernet Define the PHY address Signed-off-by: Arpit Goel <B44344@freescale.com> Signed-off-by: Bhupesh Sharma <bhupesh.sharma@freescale.com> Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> [York Sun: remove dash from commit message] Signed-off-by: York Sun <yorksun@freescale.com>
