Some fixes for the BCOM WinNET100, mostly in Config.lb:

- Add missing entry for the NIC:

     device pci 0f.0 on end           # Ethernet (onboard)

 - Drop the following lines:

     register "com1" = "{115200}"
     register "com2" = "{38400}"

   Those entries hardcode the BAUD rate (as far as I can tell, please
   correct me if I'm wrong). We don't want that -- instead the config option
   TTYS0_BAUD in Options.lb should be used(?) I verified that dropping those
   lines will not break serial output (COM1, 115200, 8n1).

 - Enable IDE (PCI device 00:12.2) and add the following register lines
   to tell the CS5530 code to actually enable IDE channel 0:

      register "ide0_enable" = "1"
      register "ide1_enable" = "0"     # Not available/needed on this board

   Tested with a 2.5" hard drive and FILO, works fine.

 - Enable USB (PCI device 00:13.0), not sure why it was commented.

 - Enable COM2 as it's used by the smartcard reader.

 - Add CONFIG_COMPRESSED_PAYLOAD_LZMA to Options.lb, in order to fix
   abuild for this board.

 - Add some more comments.
