Exclusive PCI hardware interrupt

Applications demanding a high-performance interrupt require a high-speed hardware
interrupt reaction. The PCI hardware interrupt should be used only by one resource in order
to ensure high-speed reaction of the hardware.
To enable this, the Ethernet 1, PROFIBUS/MPI interfaces and the two slots each have an
exclusive interrupt.
