asus/k8v-x: Add PIRQ tables to init PCI IRQ config
Pulled getpir from the attic and used data provided by it to create the table a bit more programmatically and added the AGP slot so the video card is given an IRQ Change-Id: Id3dc1a77ac6382405f5f36707994287e84e1168b Signed-off-by: Urja Rannikko <urjaman@gmail.com> Reviewed-on: http://review.coreboot.org/12350 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <pgeorgi@google.com>
