While implementing FastMode+ support for the R-Car IP core, I noticed potential for other cleanups. It turned out that it makes sense to apply them first, so here is the series. Tested on a Renesas Falcon board with an R-Car V3U. The calculated values are identical for 100 and 400kHz. The RIIC patch is build tested only. Looking forward to comments!
