  This routine should be called twice in BDS.\r
  1) The first call must be before EndOfDxe. The system capsules is processed.\r

     all capsules are processed.\r
     If not all capsules are processed, reset will be defered to second call.\r
\r
  2) The second call must be after EndOfDxe and after ConnectAll, so that all\r
     device capsule FMP protocols are exposed.\r
     The system capsules are skipped. If the device capsules are NOT processed\r
     in first call, they are processed here.\r
