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().
