tpm: add TPM2_PCR_Allocate command

TPM2_PCR_Allocate command is required to reconfigure 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.
