tpm: Implement tpm_auto_start() for TPMv1.2 (2023-02-28 09:44:33 +0200)
The CI showed no issues: https://source.denx.de/u-boot/custodians/u-boot-tpm/-/pipelines/15398
---------------------------------------------------------------- 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 ยง12.3 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.
