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.

RPMB requires digital signature of the message.  Take the implementation
of HMAC SHA256 from this place https://github.com/ogay/hmac.git



Actually this is BSD license, IANAL but according to my understanding
nothing terrible will happen if we provide all the original copyrights.

Fix the recurisve make targets by using $(MAKE).  Otherwise we get lots of
warnings and issues with parallel builds.

Fix the install target -- the man subdir was missing a dummy target.

Add proper .PHONY markings.
