Get the Ethernet working with misoc #6

The Ethernet uses the RGMII interface. LiteEth in misoc currently doesn't support RGMII interfaces - see https://github.com/m-labs/misoc/issues/5 for more information.

Hence;

[x] Add support to RGMII to LiteEth
[x] Get it working with the opsis board

A quick work around might be to use an existing RGMII to GMII interface converter.

This has been done by florent for the HDMI2Eth firmware (https://github.com/timvideos/HDMI2USB-misoc-firmware/blob/master/targets/opsis_base.py#L178) and the GMII interface was integrated into LiteEth https://github.com/enjoy-digital/liteeth

There is an open issue for getting gigabit working reliably for the HDMI2Eth (see https://github.com/timvideos/HDMI2USB-misoc-firmware/issues/32 ) but Gigabit works with liteEth.
