[U-Boot] [PATCH v2 2/2] sunxi: A64/Pine64: (re-)add sun8i emac DT nodes

[Andre Przywara]

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.
