Otherwise, busses that implement the pcib interface that forget to
implement pcib_route_interrupt would return EIO, which the caller
interprets as 'use interrupt 6'. This is likely the cause of much of
the grief that we had when I enabled power modes for the cardbus
bridge, since the card needed to reroute the interrupt to it and it
was getting 6 which was d by the pccbb sanity checks.
- Improve the formatting for devices identified by the database.
- Fix the pcib_route_interrupt method definition, as an old version
snuck in here somehow 8(
- Remove a couple of the vendor/device IDs for PCI:ISA bridges which
correctly identify themselves.

like the args to the config space accessors these functions replaced.
This reduces the likelyhood of overflow when the args are used in
macros on the alpha. This prevents memory management faults when
probing the pci bus on sables, multias and nonames.

the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
which call busspace.
* Rework pci config accesses to route through the pcib device instead of
calling a MD function directly.
With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.
