dma_request_channel() calls into __dma_request_channel() with NULL as value for np, which won't allow for the selection of the correct DMAC when multiple DMACs are available. Switch to using __dma_request_channel() directly so that we can choose the desired DMA for the channel. This is in preparation of adding DMAC support for the Renesas RZ/V2H(P) and similar SoCs.
