[PATCH 9/9] arm64: dts: marvell: armada-3720-gl-mv1000: Add switch fixed-link

["Rob Herring (Arm)" <robh@kernel.org>]

As the switch port 0 has an 'ethernet' phandle, 'phy-mode' and one of
'fixed-link', 'phy-handle' or 'managed' are required by the DSA schema.
The expressobin has appears to have a similar configuration, so copy it
and use 'fixed-link'.
