ASoC: rsnd: care DMA slave channel name for DT
Renesas sound driver is supporting to use DMAEngine. But, DMA slave channel name "tx", "rx" is not enough in DT case. Becuase, it has many ports and path combination. This patch adds rsnd_dma_of_name() to find DMA channel name, for example memory to SSI0 is "mem_ssi0", SSI0 to memory is "ssi0_mem", SSI0 to SRC0 is "ssi0_src0", SRC0 to SSI0 is "src0_ssi0", SRC0 to DVC0 is "src0_dvc0"... Renesas sound want to use PIO transfer mode for some reasons. It will be PIO tranfer mode if device node doesn't have DMA settings.
