Routine Description:

  This routine adds the PPI/Protocol Hobs that are consumed by the DXE Core.
  Normally these come from PEI, but since our PEI was 32-bit we need an
  alternate source. That is this driver.

  This driver does not consume PEI or DXE services and thus updates the 
  Phit (HOB list) directly

Arguments:

  HobStart - Pointer to the beginning of the HOB List from PEI

Returns:

  This function should after it has add it's HOBs
