GPEX driver is not registering a callback to route INTx and
pci_device_route_intx_to_irq() throws a following warning
"PCI: Bug - unimplemented PCI INTx routing".
It also returns -1 as an interrupt number as well as marking it as a
disabled one.
Hence to complete the GPEX driver in terms of INTx routing I have
added this patch but at the same time routing works without this
patchset :) .
