First round of i82801ax clean-ups (trivial).
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).
