Here is a series paving the way for Gen4 support. This time we properly
apply the Gen3 specific features. See the patch comments for further
information and changelogs. This has been tested on a Renesas Falcon
board with a R-Car V3U SoC at various bus speeds. Because the
calculation formulas are crucial, testing on board farms would be much
appreciated!

Thanks and happy hacking!
