 1.7  11-Sep-2021  andvar Add missing double p and d for stopped and overriden accordingly.
Fix few more typos along the way, mainly in copy-pasted comments.
 1.6  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.5  24-Apr-2021  thorpej branches: 1.5.8;
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?).
 1.4  09-Jun-2015  matt branches: 1.4.32;
#include <sys/cpu.h> or <mips/cpuregs.h> as needed
 1.3  28-Apr-2008  martin branches: 1.3.44; 1.3.64;
Remove clause 3 and 4 from TNF licenses
 1.2  29-Mar-2008  tsutsui branches: 1.2.2; 1.2.4; 1.2.6;
Split softc and device_t for zsc(4) and its children.

XXX we should restructure MI APIs and make it really machine independent.
 1.1  27-Mar-2008  tsutsui Add kernel support for optional Z85C30 serial console on Cobalt Qube 2700.
There is some interrupt related issue (in MI z8530tty driver?) on heavy load,
but useful enough for debugging.
 1.2.6.1  16-May-2008  yamt sync with head.
 1.2.4.1  18-May-2008  yamt sync with head.
 1.2.2.3  02-Jun-2008  mjf Sync with HEAD.
 1.2.2.2  03-Apr-2008  mjf Sync with HEAD.
 1.2.2.1  29-Mar-2008  mjf file zs.c was added on branch mjf-devfs2 on 2008-04-03 12:42:13 +0000
 1.3.64.1  22-Sep-2015  skrll Sync with HEAD
 1.3.44.1  03-Dec-2017  jdolecek update from HEAD
 1.4.32.1  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.
 1.5.8.1  03-Aug-2021  thorpej Adapt to CFARGS().
