Marc-André Lureau	b9777bb42e	OvmfPkg: add Tcg2PhysicalPresenceLibQemu ... Cloned "SecurityPkg/Library/DxeTcg2PhysicalPresenceLib" and: - removed all the functions that are unreachable from Tcg2PhysicalPresenceLibProcessRequest() [called from platform BDS], or SubmitRequestToPreOSFunction() and ReturnOperationResponseToOsFunction() [called from Tcg2Dxe]. - replaced everything that's related to the TCG2_PHYSICAL_PRESENCE*_VARIABLE variables, with direct access to the QEMU structures. This commit is based on initial experimental work from Stefan Berger. In particular, he wrote most of QEMU PPI support, and designed the qemu/firmware interaction. Initially, Stefan tried to reuse the existing SecurityPkg code, but we eventually decided to get rid of the variables and simplify the ovmf/qemu version.
