mmc: report capacity for the selected partition
Enhance the MMC core to calculate the size of each MMC partition, and update mmc->capacity whenever a partition is selected. This causes: mmc dev 0 1 ; mmcinfo ... to report the size of the currently selected partition, rather than always reporting the size of the user partition.
