When KeyChain loading PIB and TPM, it will check the consistency between the TPM and the TPM locator in PIB.
Under different configuration, KeyChain may change the TPM locator in PIB and reset the database, or change the TPM locator only.
However, current implementation of PIB mixed the TPM locator modification together with database resetting, which will complicate the KeyChain logic.
It would be better to separate these two operations into two different methods, so that KeyChain can invoke the necessary method(s) only.
