There is a SoC between dwc and DMA block (ie. PL330) that does not have a burst signal and supports only single.
So write not-support-burst property on dts, it support single DMA mode.
This feels like something we ought to be discovering from the DMA API somehow, while it's not quite a property of the DMA controller (but rather of the SoC integration) in this case it could be a property of some DMA controller elsewhere and the whole process of finding and figuring out the properties of the DMA controler is handled by the DMA API.
