ARM: dts: exynos: Fix port nodes names for Exynos5420 Peach Pit board
Commit bea7eef6949c ("ARM: dts: exynos: Fix DTC unit name warnings in Peach Pit") fixed the DTC warnings about mismatches between unit names and reg properties in the Exynos5420 Peach Pit DTS. But unfortunately it also added a regression on the Peach Pit when changing the port node names since the OF graph logic expects the port nodes to be always named 'port'. The Documentation/devicetree/bindings/graph.txt binding document says that when there is more than one port, '#address-cells', '#size-cells' and 'reg' properties should be used to number the port nodes.
