The pl330 DMA controller provides number of DMA channels and requests through its registers, so duplicating this information (with a chance of mistakes) in DTS is pointless. Additionally the DTS used always wrong property names which causes DT schema check failures - the bindings documented 'dma-channels' and 'dma-requests' properties without leading hash sign. Another reason is that the number of requests also does not seem right (should be 8).
