sdk: dts: ls104x move dma-coherent from soc to its child nodes
Since SMMU is not supported for SDK version, USB function will down if
still apply property 'dma-coherent' in scope of soc (USB driver is not
ready to support it alone) in SDK device trees, decide to remove it.
And add dma-coherent on other non-USB child nodes under soc.
dma-coherent feature in dts node will cause issue that
QE-HDLC received too little, when a lot of data is transmitted while
just little data received, the Tx buffer will run out.
