As the kernel DT does not have an Ethernet driver and bindings, lets add the DT bindings for U-Boot's sun8i EMAC Ethernet driver as a U-Boot specific DT include. This re-adds the nodes that got lost when syncing the kernel DT to U-Boot. Compared to the former bits it slightly updates the DT nodes to adapt to the new DT (clock and reset nodes), but keeps the rest the same to let it work with the existing U-Boot driver.
