mmc: Allow host drivers to specify max block count
Many controllers have an upper limit on the number of blocks that can be transferred in one request. Allow the host drivers to specify this and make sure we avoid hitting this limit. Also change the max_sectors field to avoid confusion. This makes it map less directly to the block layer limits, but as they didn't apply directly on MMC cards anyway, this isn't a great loss.
