[coreboot] Net and virtio problem with QEMU 0.10.0 and coreboot v2

[rukhsana ansari]

Ron,

The following was the irq_tables.c file created when getpir was run with
QEMU using its default Bochs BIOS.

#ifdef GETPIR
#include "pirq_routing.h"
#else
#include <arch/pirq_routing.h>
#endif

const struct irq_routing_table intel_irq_routing_table = {

    0x00,         /* Where the interrupt router lies (bus) */
    (0x01<<3)|0x0,   /* Where the interrupt router lies (dev) */
    0,         /* IRQs devoted exclusively to PCI usage */

    {
