- This function returns the pointer to first HOB in the list.
- For PEI phase, the PEI service GetHobList() can be used to retrieve the pointer
- to the HOB list. For the DXE phase, the HOB list pointer can be retrieved through
- the EFI System Table by looking up theHOB list GUID in the System Configuration Table.
- Since the System Configuration Table does not exist that the time the DXE Core is
- launched, the DXE Core uses a global variable from the DXE Core Entry Point Library
- to manage the pointer to the HOB list.

- If the pointer to the HOB list is NULL, then ASSERT().
