OvmfPkg/Tcg2ConfigPei: skip TPM-1.2 detection when building for ARM/AARCH64
Dating back to commits f5cb3767038e and ddd34a818315d, the
"ArmVirtPkg/ArmVirtQemu.dsc" platform includes the
"OvmfPkg/Tcg/Tcg2Config/Tcg2ConfigPei.inf" module when the TPM2_ENABLE
build flag is defined.
This was regressed in commit 89236992913f, which added a Tpm12DeviceLib
dependency to Tcg2ConfigPei. "ArmVirtQemu.dsc" does not resolve that class
to any instance, so now we get a build failure:
> build.py...
> ArmVirtPkg/ArmVirtQemu.dsc(...): error 4000: Instance of library class
> [Tpm12DeviceLib] is not found
> in [OvmfPkg/Tcg/Tcg2Config/Tcg2ConfigPei.inf] [AARCH64]
> consumed by module [OvmfPkg/Tcg/Tcg2Config/Tcg2ConfigPei.inf]
The TPM-1.2 code in OvmfPkg/Tcg2ConfigPei is limited to a special use case
(a kind of physical TPM-1.2 assignment), and that has never applied to
"ArmVirtQemu.dsc".
Short-circuit the TPM-1.2 detection in the ARM/AARCH64 builds of
OvmfPkg/Tcg2ConfigPei, removing the Tpm12DeviceLib dependency.
Functionally, this patch is a no-op on IA32 / X64.
