mmc-utils: RPMB: add HMAC SHA256 support
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.
