commit ca369d51b3e1 ("block/sd: Fix device-imposed transfer length limits")
introduced max_dev_sectors as upper limit for max_hw_sectors. This caused
limitation of maximum block size to default max_dev_sectors value - 127,
causing performance degradation with higher block sizes.
This patchset is allowing mmc driver to override max_dev_sectors value.
