Subject: [PATCH 21/21] arm64: dts: ls104x: make dma-coherent global to the SoC

From: Laurentiu Tudor <laurentiu.tudor@....com>

These SoCs are really completely dma coherent in their entirety so add
the dma-coherent property at the soc level in the device tree and drop
the instances where it's specifically added to a few select devices.
