mmc: renesas_sdhi: limit block count to 16 bit for old revisions
R-Car Gen2 has two different SDHI incarnations in the same chip. The older one does not support the recently introduced 32 bit register access to the block count register. Make sure we use this feature only after the first known version. Thanks to the Renesas Testing team for this bug report!
