This series of patches fixes the TPM SPAPR device model so that it reacts
in the same way as the other device models do when the backend device did
not start up properly. It now calls exit(1).

Due to a change in the TPM 2 code, the pcrUpdateCounter (14th byte) in the
TPM2_Pcrread response now returns a different value than before. So it's
better to skip the 14th byte when comparing expected against actual responses.

   Stefan

v2->v3:
  - more elaborate commit messages

v1->v2:
  - simplified skipping of 14th byte in response

  tpm: tpm_spapr: Exit on TPM backend failures
  tests: tpm: Skip over pcrUpdateCounter byte in result comparison
