* Rename CommandAttribute as CommandHIpcAttribute to prepare for 12.x changes * Implement inital support for TIPC and adds SM command ids * *Ipc to *ipc * Missed a ref in last commit... * CommandAttributeTIpc to CommandAttributeTipc * Addresses comment and fixes some bugs around TIPC doesn't have any padding requirements as buffer C isn't a thing Fix for RegisterService inverting two argument only on TIPC
