OVMF BDS: Don't call BdsLibSaveMemoryTypeInformation
This call can cause a reset, and is most critical for ACPI S3/S4 resume situations. OVMF does not support S3/S4. OVMF does not have true non-volatile variable support, so this call could cause a continuous reset situation in certain scenarios. (The BdsLibSaveMemoryTypeInformation may set an non-volatile variable, and then reset with the assumption that the variable will still exist during the next boot.) Additionally, some version of QEMU appear to hang when the port 64 reset is initiated. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10927 6f19259b-4bc3-4df7-8a09-765794883524
