arm: dts: sunxi: update H3 to new EMAC binding
The U-Boot driver for the sun8i-emac was using some preliminary DT
binding. Now since Linux got its own driver in v4.15 and our driver
can now cope with both bindings, let's convert the DT nodes used by the
various H3 boards over to the new bindings used by the kernel.
