Put Framework SMM CPU I/O Protocol into its own .h file and add the GUID for this protocol to the DEC file.
Some definitions are shared between the Framework SMM CPU I/O Protocol and the PI SMM CPU I/O 2 Protocol, so SmmCpuIo.h include SmmCpuIo2.h from the MdePkg git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9736 6f19259b-4bc3-4df7-8a09-765794883524
