Fix computation of the appropriate auto-vector interrupt level to use
for the DMA controller by tracking all of the DIO devices that have
"ISRPRI_BIO" interrupt handlers, and finding the highest auto-vector
level among them and informing the DMA controller.

Previously, in a post-flattening world, the DMA controller was always
told to interrupt at lev5, which is fine I guess although definitely not
ideal, but would not work on aaaancient HP320 Rev A DMA boards. To that
effect, print a warning if a Rev B DMA board ends up at ipl != 3 (we can't
differentiate between a Rev A and a Rev B board).

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Remove trailing spaces.

Split device_t/softc, and misc cosmetic changes.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

Use bus_space_map(9) and bus_space_vaddr(9) rather than iomap().

Some KNF.

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

Use ANSI function decls, static, and const.

Add "oddbyte" bus_space(9) access ops for DIO devices which have
odd byte address space.

Modify hp300 bus_space(9) structures/functions to add hooks to override

Clean-up the DIO bus. Includes two main changes:

1) Pass address and ipl locators at attachment;
2) Remove hack which made the internal HP-IB controller
look like a DIO device.

The hack to allow the nhpib driver to support internal and DIO
controllers appears to be a leftover from 4.3BD where it was not
possible to have a driver attach to different busses. NetBSD has
supported bus-dependent attachments for a long time.
