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?).

Add PXA25x based Zaurus SL-C700/750/760/860 support.

All porting work was done by TOYOKURA Atsushi, with
several minor adjustments for integration by me and nonaka@.

Add PXA25x based Zaurus SL-C700/750/760/860 support.

All porting work was done by TOYOKURA Atsushi, with
several minor adjustments for integration by me and nonaka@.

His SL-C700 first running NetBSD/zaurus was demonstrated on
NetBSD booth at Open Source Canference 2011 Tokyo/Fall:
http://www.NetBSD.org/gallery/events.html#opensourceconf2011-tokyofall

Note GENERIC kernel works on SL-C750/760/860 (and C1000/3x00) but for now
SL-C700 requires its own kernel with special KERNEL_BASE_PHYS address
due to zbsdmod.o loader restriction (probably caused its small 32MB RAM).
