  36 Routine Description:
  37   Return the FD Size and base address. Since the FD is loaded from a
  38   file into Windows memory only the SEC will know it's address.
  39
  40 Arguments:
  41   Index  - Which FD, starts at zero.
  42   FdSize - Size of the FD in bytes
  43   FdBase - Start address of the FD. Assume it points to an FV Header
  44
  45 Returns:
  46   EFI_SUCCESS     - Return the Base address and size of the FV
  47   EFI_UNSUPPORTED - Index does nto map to an FD in the system
