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.
