This core implememts AES KEY WRAP as defined in RFC
3394 and the keywrap with padding
according to RFC 5694
The user/host system writes data to be wrapped/unwrapped to the core as
well as the wrapping key. The core then handles the wrapping/unwrapping
operation independently. When operation has completed the result can be
read back.
Initial design has just been started. Does not work. Do not use.
