b8c637864a6904a9ba8e0df556d5bdf9f26b2c54 (ASoC: rsnd: use regmap_mmio instead of original regmap bus) added regmap_mmio support on Renesas R-Car sound driver. Then, debug information of register read/write indicates regmap index, not register address. This is a little bit confusable information. This patch tidyup debug message, and added regmap debug hint on comment area.
