[PATCH 2/2] ARM: dts: meson8b-odroidc1: ethernet support

[Emiliano Ingrassia]

The Odroid-C1+ board is equipped with an RTL8211F ethernet PHY
which supports 10/100/1000 Mbps ethernet.
This patch adds the PHY description to the board DT,
setting the maximum speed to 1 Gbps, and enables the ethernet controller.
