- Add a void pointer to the ata-pci controller softc to allow

  chipset-specific code to attach chipset-specific data.
- Use chipset-specific data in the acard and promise chipsets rather than
  changing the ivars of ATA PCI devices.  ivars are reserved for use by the
  parent bus driver and are _not_ available for use by devices directly.
  This fixes a panic during sysctl -a with certain Promise controllers with
  ACPI enabled.
