foo_pcib_[read|write]_config() functions rather than relying on
a break or return being in the CFG macro.
This fixes a panic later in the boot process on a UP1000. From
inspection, it looks like this fixes a similar problem in the tsunami code.

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.
Only PCI and on-board ISA peripherials are supported at this time.
This support has been only lightly tested due to a lack of response to my
call for testers on the freebsd-alpha mailing list. It works quite well
on the one AS2100 on which it has been tested, but it may not work on
an AS2100A and should therefore be regarded as experimental.
