1. Removed #ifdef SNP_DEBUG and used debug lib to output information
2. Rename PcdPlatformNoCsmSupport to PcdPlatformCsmSupport. 3 Removed #ifdef EFI_NO_CSM and used PcdPlatformCsmSupport. 4. Removed #ifdef ALIGNMENT from C Variable.c and added 2 files Variable/Pei/Ipf/VariableWorker.c and Variable/Pei/VariableWorker.c git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@2487 6f19259b-4bc3-4df7-8a09-765794883524
