  tpm: Implement tpm_auto_start() for TPMv1.2 (2023-02-28 09:44:33 +0200)

----------------------------------------------------------------
Due to U-Boot's lazy binding we always relied on command line tools
to initialize the TPM subsystem and devices.  One exception is the EFI
subsystem.  When compiled with TCG2 measured boot support the TPM was
automatically initialized.

However that init was not complete.  The TCG specs [0] (and specifically
§12.3 Self-test modes) describe how self-tests on the device should be
performed.  This PR is adding an extra API function, that can be used to
initialize the TPM2.0 properly.

Simon added the equivalent for TPM1.2 and refactored the DM tests to include
the new funtion.
