fpga: Fix Spartan II FPGA booting

Browse Source 
This patch does some minor fixing of the Xilinx Spartan II
FPGA boot code:

- Fixed call order of post configuration callback and
  success message printing (result of copy-paste?)
- relocate post configuration callback only when it
  is implemented
- remove obsolete comment
- minor coding style cleanup
