The latest TPM specification uses different command codes, command
structures and return codes.
Let's put definitions for different TPM versions into different
include files.
CQ-DEPEND=CL:357831
BRANCH=none
BUG=chrome-os-partner:50645
TEST=with the rest of the patches applied kevin/gru boards boot into
chrome OS with rollback counters read from/written to TPM2
