UEFI231 spec compliance:
UEFI231 defines EFI_SMM_COMMUNICATION_ACPI_TABLE. We should move it from Pi/ dir to Uefi/ dir. UEFI231 defines EFI_SMM_COMMUNICATE_HEADER. We should move it from Protocol/SmmCommunication.h to Uefi/ dir. The original file will still include the new data structure to keep compatibility. signed-off-by: jyao1 reviewed-by: rsun3 git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12724 6f19259b-4bc3-4df7-8a09-765794883524
