This series implements 2 missing TPM related firmware API calls. One is to
get the maximum TPM command size and the other one allows passing a TPM
command through to the TPM. These calls will be used by ppc64-enablement of
the following grub series where grub calls similar API calls in the x86
firmware:

v2:
  - Added explanation what the API calls will be used for
  - Improved commit messages
