When resume from S3 and CPU loop mode is MWait mode, if driver calls APs to do task at EndOfPei point, the APs can't been wake up and bios hang at that point. The root cause is PiSmmCpuDxeSmm driver wakes up APs with HLT mode during S3 resume phase to do SMM relocation. After this task, PiSmmCpuDxeSmm driver not restore APs context which make CpuMpPei driver saved wake up buffer not works. The solution for this issue is let CpuMpPei driver hook S3SmmInitDone ppi notification. In this notify function, it check whether Cpu Loop mode is not HLT mode. If yes, CpuMpPei driver will set a flag to force BSP use INIT-SIPI -SIPI command to wake up the APs.
