irq: change io_apic_set_pci_routing() to use device parameter

Make actual use of the device parameter passed down to
io_apic_set_pci_routing() - to have the IRQ descriptor
on the home node of the device.

If no device has been passed down, we assume it's a platform
device and use the boot node ID for the IRQ descriptor.

[ Impact: optimization, make IO-APIC code more NUMA aware ]
