eepro100: Improve support for different devices

eepro100: Improve support for different devices

* Add device properties (size of statistical data,
  extended tcb support) to EEPRO100State and set
  these values for the different devices.

* Fix PCI configuration for existing devices.

* Add initialisation code for missing devices.

* Remove function device_supports_eTxCB.
  It is no longer needed.

* Fix dump of statistical data. It now respects
  the real size of the statistical data.
  An endianess issue was fixed here, too.

* CU_SHOWSTATS, CU_DUMPSTATS now write a
  completion value after the statistical data.
  There is no need to keep this value in
  eepro100_stats_t, so member "complete"
  could be removed.
