Subject: [PATCH v3 5/9] arm64: dts: ls1046a: make dma-coherent global to the SoC

LS1046a is mostly dma coherent with a few exceptions(e.g. edma) 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.
Also use the newly added dma-noncoherent property for exceptions.
