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

[Andre Przywara <andre.przywara@arm.com>]

As the kernel DT does not have an Ethernet driver and bindings, lets
(re-)add the DT bindings for U-Boot's sun8i EMAC Ethernet driver, which
got lost when syncing the kernel DT to U-Boot.
This 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.
