The Kria boards start the TPM with a 'tpm autostart' call in the board environment. Enable CONFIG_TPM_AUTOSTART instead and drop tpm_setup from the environment, so the TPM is started even when the preboot script is changed or skipped.
The TPM is now started before preboot, so the TPM reset hints for some carrier card revisions are printed after the startup. Boards which still have the old environment saved run 'tpm autostart' a second time, which is harmless.
