mmc: show the erase group size and HC WP group size in mmcinfo output
This adds the erase group size and high-capacity WP group size to mmcinfo's output. The erase group size is necessary to properly align erase requests on eMMC. The high-capacity WP group size is necessary to properly align partitions on eMMC. Signed-off-by: Diego Santa Cruz <Diego.SantaCruz@spinetix.com>
