ASoC: rsnd: add struct rsnd_dai_platform_info
R-Car sound DAI consists from SSI/SCU/SSIU/SRU... Current R-Car sound DAI is decided from these settings, but it is intuitively unclear, and is not good design for DT support. This patch adds new rsnd_dai_platform_info to solve this issue. But now, many platform is using this driver without rsnd_dai_platform_info. So, this patch still supports DAI settings via SSI to keep compatible. It will be removed in next Linux version.
