The latest PiSmmCore driver added several debug messages in the function SmmAddMemoryRegion in Page.c. The function SmmAddMemoryRegion is called by the library constructor PiSmmCoreMemoryAllocationLibConstructor. When PiSmmCoreMemoryAllocationLibConstructor is executed, the constructor of DxeHobLib (HobLibConstructor in HobLib.c) is not executed yet. But platform instance of DebugLib may need get hob before printing any message. As a result, an ASSERT happens in the function GetHobList. The patch is to update GetHobList to get HOB list from system configuration table when the HOB list is not retrieved and not cached yet, and HobLibConstructor is also to be updated to just call GetHobList.
