    This add 2M huge gtt support for GVTg. Unlike 64K gtt entry, we can
    shadow 2M guest entry with real huge gtt. But before that, we have to
    check memory physical continuous, alignment and if it is supported on
    the host. We can get all supported page sizes from
    Finally we must split the 2M page into smaller pages if we cannot
    satisfy guest Huge Page.
