Historically, we have been using MMC_CAP* to handle host HW issues and currently the block layer uses MMC_CAP2_NO_MULTI_READ flag for a multi I/O HW bug workaround. There are a few tweaks needed to make MMC_CAP2_NO_MULTI_READ suite all situations. Therefore let's add an optional host ops callback to enable host drivers to return the number of blocks it allows per request. In a future patch and when host drivers have converted to the new callback, MMC_CAP2_NO_MULTI_READ shall be removed.
