[SLOF] [PATCH v4 16/33] tpm: Add TPM firmware API call reformat-sml-to-efi-alignment

[Stefan Berger]

This patch adds support for the TPM firmware API call
reformat-sml-to-efi-alignment. It also adds the required
entry 'ibm,sml-efi-reformat-supported' entry to the
/vdevice/vtpm node. This entry indicates that the API
call exists.
