 1.13  25-Jan-2022  nisimura - rectify attach messages.
- abandon irq to use for now.
 1.12  21-Dec-2021  nisimura improve consistency when attach error cases.
 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?).
 1.9  27-Jan-2021  thorpej branches: 1.9.2;
Rename of_match_compat_data() to of_compatible_match(). Similarly,
rename of_search_compatible() to of_compatible_lookup().

Standardize on of_compatible_match() for driver matching, and adapt
all call sites.
 1.8  31-May-2020  thorpej branches: 1.8.2;
Remove superfluous checking for a "disable" property in the device_t
properties dictionary.

 1.7.4.1  25-Mar-2020  martin file sni_gpio.c was added on branch phil-wifi on 2020-04-13 08:03:37 +0000
 1.8.2.1  03-Apr-2021  thorpej Sync with HEAD.
 1.9.2.1  23-Mar-2021  thorpej Convert config_found_ia() call sites where the device only carries
a single interface attribute to bare config_found() calls.
 1.10.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
