AP should not use PeiServices. The patch serial fix one issue related to this.
This serial also include one patch used to refine the debug message.

V3:
1. Define union to specify the ppi or protocol.
V2:
1. Initialize CpuFeaturesData->MpService in CpuInitDataInitialize
and make this function been called at the begin of the
initialization.
2. let all other functions use CpuFeaturesData->MpService install
of locate the protocol itself.
V1:
GetProcessorIndex function calls GetMpPpi to get the MP Ppi.
Ap will calls GetProcessorIndex function which final let AP calls
PeiService.
This patch avoid GetProcessorIndex call PeiService.
