On Renesas R-Car SDHI hardware, we sometimes had timeouts accessing the RPMB. This is because AutoCMD23/12 features needs a properly filled sbc to work correctly. But RPMB sends an individual CMD23. I could have fixed the driver but after some research concluded that fixing the core seems the proper thing to do. Tested on a R-Car M3-N. No timeouts showed up anymore.
Changes since RFC: * dropped sanity checks on block count size * added comment why we don't do sanity checks * rebased to current mmc/next * added Tested-tags from Clément, thanks!
