Routine Description:
  Return the FD Size and base address. Since the FD is loaded from a 
  file into Windows memory only the SEC will know it's address.

Arguments:
  Index  - Which FD, starts at zero.
  FdSize - Size of the FD in bytes
  FdBase - Start address of the FD. Assume it points to an FV Header

Returns:
  EFI_SUCCESS     - Return the Base address and size of the FV
  EFI_UNSUPPORTED - Index does nto map to an FD in the system
