R-Car sound DMA will be used from SSI/SRC. dma.c doesn't alloc DMA handler in .probe timing, because we don't know what kind of DMA transfer will be used then. Thus, SSI/SRC have *rsnd_mod for DMA. rsnd_dma_attach() will allocate it and attach it to system. It will be PIO mode if it can't alloc DMA handler. In case of MIX is used, rsnd_dma_attach() will be called twice from SSI. To avoid duplicate allocation, current rsnd_dma_attach() is checking allocated DMA handler. This DMA related operation is a little bit difficult to understand. This patch adds new rsnd_dma_alloc() and separates allocation and attach for readable code.
