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!

Wolfram Sang (2):
  mmc: core: use mrq->sbc when sending CMD23 for RPMB
  mmc: core: remove obsolete mmc_set_blockcount() function
