[U-Boot] [PATCH 1/6] sunxi: A64: dts: replace EMAC .dtsi with symlink

[Andre Przywara]

Currently we add the U-Boot specific Ethernet MAC DT nodes for the
Pine64 via a board-specific add-on .dtsi.
However these nodes and properties in there are actually pretty generic
for all A64 boards which use a PHY connected via RGMII.
Rename the add-on .dtsi to reflect this and make the Pine64 .dtsi a
symlink to this new file.
This simplifies letting other boards use the EMAC too.
