 1.11  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.10  24-Apr-2021  thorpej branches: 1.10.8;
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?).

#include <sys/bus.h> instead of <machine/bus.h>.

struct device * -> device_t
struct cfdata * -> cfdata_t
use bool when appropriate
some constification
 1.7  06-Jun-2011  matt More device_t, cfdata, CFATTACH_DECL_NEW cleanup.
 1.6  28-Apr-2008  martin branches: 1.6.22; 1.6.32;
Remove clause 3 and 4 from TNF licenses
 1.5  11-Dec-2005  christos branches: 1.5.74; 1.5.76; 1.5.78;
merge ktrace-lwp.
 1.4  13-Sep-2004  drochner use config_found() instead of config_found_sm() if no submatch
function is used
 1.3  25-Jul-2003  scw Switch ibm4xx ports to common powerpc bus_space/bus_dma code.
XXX: Walnut PCI support is broken. This will be addressed shortly.

- Supported devices: le, com, lpt, pckbd, frame buffer.
- Support missing: phy, audio, pcmcia.
- Boots from network or md.

 1.6.22.1  12-Jun-2011  rmind sync with head
 1.9.68.1  21-Mar-2021  thorpej Give config_found() the same variadic arguments treatment as
config_search(). This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls. Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.
 1.10.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
