Marc-André Lureau 8923699291 OvmfPkg: detect TPM 1.2 in Tcg2ConfigPei ... Complement commit 6cf1880fb5 ("OvmfPkg: add customized Tcg2ConfigPei clone", 2018-03-09) by detecting TPM 1.2 devices. Since Tpm12RequestUseTpm() returns success on any TPM interface, (including FIFO & CRB which are TPM 2.0), try to send a GetTicks TPM 1.2 command to probe the version. In case of failure, fallback on TPM 2.0 path.
