Volker Ruppert f65c4e66b8 - debugger command 'info device': implemented support for additional arguments
- ne2k: replaced debugger command 'info ne2k' completely by a new version based
  on 'info device' with additional arguments and removed all of the now obsolete
  stuff (ne2k device stub, macro for print_info())
- pci: added option 'dump=full' for the debugger command 'info device' to show
  the whole PCI config space
- TODO: some other devices could have support for additional options in
  debug_dump()
