    tpm2: add marshaling/unmarshaling layer
    
    TPM commands need to be serialized (marshaled) to be sent to the
    device, and the responses need to be de-serialized (unmarshaled) to be
    properly interpreted by upper layers.
    
    This layer does not exist in TPM1.2 coreboot implementation, all TPM
    commands used there were hardcoded as binary arrays. Availability of
    the marshaling/unmarshaling layer makes it much easier to add new TPM
    commands to the code.
    
    Command and response structures used in these functions are defined in
    Parts 2 and 3 of the TCG issued document
