  To handle a special case, more than 1 PCI devices which has the same VID/DID 
  exist on the system but not all of them has PCI option ROM to be loaded. 
  So provide an OEM service, let project owner to decide if this device has 
  PCI Option ROM to be loaded or not. if SkipGetPciRom is TRUE, 
  means there is no option ROM for this device, otherwise, 
  option ROM described on PCI Option ROM table will be loaded for this device. 
  This OEM service will only be invoked if the VID/DID of PCI device could be found in PCI Option ROM Table.

  @param[out] *SkipGetPciRom        If SkipGetPciRom == TRUE means that there is no

  @retval     EFI_UNSUPPORTED       Returns unsupported by default.
  @retval     EFI_SUCCESS           The service is customized in the project.
