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

BRANCH=none
BUG=chrome-os-partner:50645
TEST=with the rest of the patches applied it is possible to
successfully initialize firmware and kernel TPM spaces.
