Today's MpInitLib PEI implementation directly calls PeiServices->GetHobList() from AP which may cause racing issue. This patch fixes this issue by duplicating IDT for APs. Because CpuMpData structure is stored just after IDT, the CpuMPData address equals to IDTR.BASE + IDTR.LIMIT + 1. v2: 1. Add ALIGN_VALUE() on BufferSize. 2. Add ASSERT() to make sure no memory usage outside of the allocated buffer. 3. Add more comments in InitConfig path when restoring CpuData[0].VolatileRegisters.
