Also refactor bus_space_map(9) and fix (unused) bus_space_mmap(9).
 1.18  04-Feb-2023  tsutsui Remove trailing spaces and TABs.
 1.17  03-Feb-2023  tsutsui Misc KNF and cosmetics.
 1.16  07-Aug-2021  thorpej branches: 1.16.6;
Merge thorpej-cfargs2.
 1.15  24-Apr-2021  thorpej branches: 1.15.8;
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?).

 1.10  30-Jun-2005  drochner branches: 1.10.2;
adaptions to config_search() change, and minor autoconf fixes, mostly from Havard Eidnes
 1.9  19-Jan-2005  chs de-__P, remove register, ansify.
 1.8  15-Jul-2003  lukem branches: 1.8.8;
__KERNEL_RCSID()
 1.7  01-Jan-2003  thorpej branches: 1.7.2;
Use aprint_normal() for cfprint routines.
 1.6  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.5  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.4  27-Sep-2002  thorpej Introduce a new routine, config_match(), which invokes the
cfattach->ca_match function in behalf of the caller. Use it
rather than invoking cfattach->ca_match directly.
 1.3  11-Sep-2002  mycroft Comprehensive patches from Christian Limpach:
* Fix problems with the DMA and SCSI drivers.
* Make turbo machines sort of work.
Additional fixes from me:
* Determine if we're a turbo at boot time, by looking at the ROM machine type.
* Set the display size correctly (1120 pixels wide, but padded to 1152 only on
non-turbo machines).
Caveats:
* SCSI doesn't work on the turbo (or at least it blows chunks with no devices
attached).
* Media selection doesn't work on the turbo (the BMAP stuff doesn't exist on
turbo machines).
* The boot block is prone to timing out.

 1.14.68.6  05-Apr-2021  thorpej Treat config_probe() as if it were a boolean function; don't compare
return value > 0... except for the odd balls, which are now really easy
to spot.
 1.14.68.5  05-Apr-2021  thorpej config_match() -> config_probe() for the straight-forward indirect config
cases. There are still a few odd balls using config_match() which should
be sorted out later.
 1.14.68.4  04-Apr-2021  thorpej CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
 1.14.68.3  03-Apr-2021  thorpej Give config_attach() the tagged variadic argument treatment and
mechanically convert all call sites.
 1.14.68.2  21-Mar-2021  thorpej CFARG_IATTR usage audit:

If a device carries only one interface attribute, there is no need
to specify it when calling config_search(); that specification is
meant only to disambiguate which interface attribute (which is a
proxy for "what kind of attach args are being used") is having
children attached. cfparent_match() will take care of ensuring that
any potential children can attach to one of the parent's iterface
attributes, and if the parent only carries one, no disambiguation is
necessary.
 1.14.68.1  20-Mar-2021  thorpej The proliferation if config_search_*() and config_found_*() combinations
is a little absurd, so begin to tidy this up:

- Introduce a new cfarg_t enumerated type, that defines the types of
tag-value variadic arguments that can be passed to the various
config_*() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS,
for now, plus a CFARG_EOL sentinel).
- Collapse config_search_*() into config_search() that takes these
variadic arguments.
- Convert all call sites of config_search_*() to the new signature.
Noticed several incorrect usages along the way, which will be
audited in a future commit.

s/impliment/implement/ in comment.

Remove cargo-culted '#if 0' code that was designed to produce a
compile-time error if any of the bus_space_*_8 functions was used,
but was documented that it produces a link-time error.

Misc KNF and cosmetics.

Use proper C99 int types.

Remove trailing spaces and TABs.

Handle NeXT Turbo VRAM regions properly.
Info from Andreas Grabher on port-next68k@:
