Get the MM Communication context from the MM Communication Buffer, instead of the pointer inside gMmCorePrivate. In the MmEntryPoint, check IsCommBufferValid from MM_COMM_BUFFER to decide whether the MMI is Synchronous MMI or Asynchronous MMI. If it is a Synchronous MMI, MM Core shadows the communication buffer into a internal copy, then invokes the MMI handlers, lastly copies data back to the MM Communication Buffer and set the return status.
