This MpService2Ppi field in SMM_S3_RESUME_STATE is used to wakeup AP to do the CPU initialization during smm s3 boot when the execution mode of PEI and DXE are the same. Currently, in CpuS3.c of smm cpu driver, BSP doesn't need to wakeup AP anymore. The initialization for AP will be done in S3Resume.c before transfer to CpuS3.c of smm cpu driver. So we can remove the MpService2Ppi field in SMM_S3_RESUME_STATE.
