dmaengine: sh: rz-dmac: Allow for multiple DMACs

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.
