[U-Boot] [PATCH v2 11/18] mmc: show the erase group size and HC WP group size in mmcinfo output

[Diego Santa Cruz]

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.
