artecgroup/dbe62: Route ethernet adapter IRQ correctly and reduce interrupt contention problems by using different IRQs for all the interrupt lines

This makes the network adapter work fully, and reduces problems on high traffic (e.g kernel oopses on fsck run over USB 2.0 HDD)
Many thanks for Peter Stuge for a lot of IRQ related help.
