  1. OvmfPkg: DxeTcg2PhysicalPresenceLib: fix changing of PCR banks 

    Tcg2PhysicalPresenceLibSubmitRequestToPreOSFunction writes to TPM2
physical presence PPI provided by coreboot (a memory region preserved
across reboots). CPU caches must be explicitly flushed prior to platform
reboot or request written to PPI will be lost.
