tpm: Switch TPMv1 over to use the new API
Take over the plain 'tpm_...' functions for use by the new TPM API. Rename all the TPMv1 functions so they are called from the API. Update the TPMv1 functions so that they are called from the API. Change existing users to use the tpm1_ prefix so they don't need to go through the API, which might introduce uncertainty.
