vboot: Add a new post code for TPM failure
If the kernel does not properly handle the TPM and send it a
TPM_SaveState command before suspend then it will not be in
the correct state on resume. In order to easily detect this
case add a new post code for TPM failure and use it in the
vboot resume path.
BUG=chromium:371105
TEST=Build and boot on wtm2.
