mmc: extend mmcinfo to show enhanced partition attribute
This extends the mmcinfo command's output to show which eMMC partitions
have the enhanced attribute set. Note that the eMMC spec says that
if the enhanced attribute is supported then the boot and RPMB
partitions are of the enhanced type.
The output of mmcinfo becomes:
