SecurityPkg/Tcg2Config: Remove use of IoLib

Remove the use of the IoLib and Mmioxx() calls to detect dTPM.
This module calls the Tpm12DeviceLib to detect a TPM and the
implementation of the Tpm12DeviceLib for dTPM performs the same
Mmioxx() calls to detect a dTPM.  This change makes this module
more generic and portable by maximizing the use of the Tpm12DeviceLib
abstraction for TPM detection.
