Subject[PATCH] ARM: dts: imx6qdl-sabresd: change phy-mode to use rgmii-id
The PHY used on the Freescale i.MX6Q/DL SABRE boards is qualified as
'rgmii' instead of 'rgmii-id'. Meaning the RX and TX delays that were
previously added by the MAC when required, but are now provided
internally by the PHY (and the MAC should no longer add the RX or TX
delays in this case).

This patch fixes the network problems seen on the Freescale i.MX6Q/DL
SABRE boards and makes a difference when correctly loading the NFS
rootfs on startup.
