New bus.h implementation/interface:
...
- No more distinction between i/o-mapped and memory-mapped
devices. It's all "bus space" now, and space tags
differentiate the space with finer grain than the
bus chipset tag.
- Add memory barrier methods.
- Implement space alloc/free methods.
- Implement region read/write methods (like memcpy to/from
bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

Correct a couple of comments ... port 0x84 produces a 1.25us delay when
...
read, not 2.5us. (I must have been confused; thanks Charles, for
correcting me.)

Map port 0x84 (which is used to generate a 2.6us delay) in isaattach().
...
Since this port is needed by at least a few drivers, export its i/o handle
via isa_attach_args.

include a machine-specific header from ARCH/isa/isa_machdep.h, to define
...
the isa_chipset_tag_t type, and to define or prototype:
isa_attach_hook()
isa_intr_establish()
isa_intr_disestablish()
i.e. the machine-dependent functions to be used my MI ISA code.
Remove prototypes for the latter two functions from this file.

pass a bus_chipset_tag_t (defined in <machine/bus.h>) to the bus when
...
attaching, and to the devices when attaching them. #include <machine/bus.h>
to make this backward compatible with old #include requirements.
Also, clean up idempotency so that isa/eisa/pci "var.h" headers are
consistent (make them all idempotent).

The IST_* and IPL_* constants are not bus-specific; don't treat them as such.

clean up several ISA device interfaces: autoconfiguration, header

inclusion, and interrupt configuration. more work still needs to be done,
but it's getting better...
