Fix various typos in comments.

Change todr_chip_handle::cookie -> todr_chip_handle::todr_dev, and
make it a device_t. Upcoming functional changes will require the
device_t associated with a TODR device.

Change todr_chip_handle::bus_cookie -> todr_chip_handle::todr_devaux.
Nothing was using the old field, but I decided to keep it around just
in cause something needs it in the future.

And with these largely mechanical yet semantically meaningful changes,
thus spake the Oracle: "Welcome to NetBSD 11.99.2."

use the inline bcdtobin and bintobcd directly instead through a macro.

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

- convert to use device_t, cfattach_t, CFATTACH_DECL_NEW etc.
- in dsrtcattach() use struct clock_ymdhms instead of rtc in DEBUG code block,
and move that block down after sc_todr.cookie is initialized so dsrtc_read() works.

New umbrella-port for PowerPC-based evaluation boards.

The first board to be included here is the port to the 405GP-based
Walnut evaluation board, which up until now lived in arch/walnut.

arch/walnut will go away soon, once all the remaining walnut-isms
in the tree have been dealt with.

Merge thorpej-cfargs2.

branches: 1.14.8;
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?).

branches: 1.13.68;
#include <sys/bus.h> instead of <machine/bus.h>.

in pbus_attach() make locs[] and pass to config_found_sm_loc()
to avoid triggering KASSERT in config_stdsubmatch().

More device_t, cfdata, CFATTACH_DECL_NEW cleanup.
