UPSTREAM: mmc-utils: Merge the lsmmc tool into mmc-utils
The lsmmc tools contains an extensive parser of the CID, CSD, SCR
registers from userspace. The utility works as-is and uses sysfs
to read the register values.
The original code is created by Sebastian Rasmussen and still lives
in an attachment in the mail archive of linux-mmc. It need to be merged
into mmc-utils repository, which is convenient for testing MMC device
from userspace.
Change since v3:
- Remove the unused EXT_CSD parser in lsmmc.c file.
