After we splitted up the old i82801xx driver which was supposed to support multiple generations of ICH* chipsets, some of the generified code is now obsolete in i82801ax which should only cover ICH/ICH0 and none of the later ICH* generations. Hence: - Drop "struct pci_driver" entries for chipsets other than ICH/ICH0. - Drop drivers for hardware that is not present on ICH/ICH0: NIC, SATA, EHCI. - Drop PIRQE-PIRQH #defines and code, not available on this chipset. - Simplify some parts of the code (more will follow).
