2. fix a print error in which a %x in format string exists but the corresponding variable argument is not present! 3. fix CONSUME_MEMORY too small issue. In X64 arch, cpu may cause the paging table is too big and beyond the pei memory scope between EfiMemoryTop and EfimemoryBottom. for example, a cpu support 44bits addressing memory space may occupied ~64M paging table. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9794 6f19259b-4bc3-4df7-8a09-765794883524
