[PATCH] classic networking: do not reference

[Pavel Pisa]

This change is required to build RTEMS with classic "--enable-networking"
and link applications/tests which reference RTEMS_BSP_NETWORK_DRIVER_ATTACH.

 Discussion: I have stumbled over problem to build some external tests
 for i386 because original integrated Ethernet drivers cannot be linked
 into application. Even that libbsd is a future goal it worth to correct
 this at least for testing. It seems that original i8259s concept
 handling is finally overcome by generic approach.
 I hope that field isOn is no longer referenced by any architecture
 or if referenced, that NULL is valid option.
 
 I am leaving for next week so I would not push this change probably.

 In the longer perspective, I think that even for these deprecated drivers
 rtems_interrupt_handler_install generic concept could/should be used.
 If it is agreed that it is right change then I can prepare patch
 for that in future.

 But I think that correction of the builds in meantime worth
 to be pushed.
