Debug Print Error level can be controled by an EFI variable. Update the DXE version of the library to use a HOB if the variable services are not yet availilbe. This allows the variable to be used early in the DXE phase. approved-by: andrewfish reviewed-by: lgao4 git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12516 6f19259b-4bc3-4df7-8a09-765794883524
