Hi Raymond,

TPM2_PCR_Allocate command is required to re-configurate a TPM device to enable or disable algorithms in run-time, thus this patch introduces the implementation of PCR allocate APIs and adds related cmd functions for testing.
To test the feature, ensure that TPM is started up. Run pcr_allocate command to turn on/off an algorithm, multiple calls are supported and all changes will be cached: `tpm2 pcr_allocate <algorithm_name> <on|off>` Run startup command with argument 'off' to shutdown the TPM. `tpm2 startup TPM2_SU_CLEAR off` Reboot the board via `reset` to activate the changes.
It would be better to have an automated test.
You could create one using the sandbox TPM, and you could add a pytest which can run on my lab (coral has a TPMv2).
