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?).

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

Change <machine/bus.h> to <sys/bus.h> throughout.

Split bus.h -> bus_{defs,funcs}.h.

Mark hpcarm/bus.h obsolete.

Make the following changes:

struct device * -> device_t
struct cfdata * -> cfdata_t
printf -> aprint_
device_t/softc split

device_private_lookup()-ification so that hpcarm (at jeast Jornada 72x)
kernels build.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

Add "name" parameter to powerhook_establish, to aid debugging. No objections
on tech-kern@

"AUTHOR" is really meant here, not "REGENTS".
Eleminate some use of #ifdef SED_DEBUG.

Clean up bogus whitespace

Cleanup:
- Apply static.
- KNF.
- Wrap long lines, unwrap short lines.

No functional changes.

Only compile in debug strings when SED_DEBUG is defined.

Split the Jornada 7xx drivers for the touch-panel, keyboard, lcd control
and power management into multiple files. This removes some dirty hacks
and improves the quality of the code.

Split the Jornada 7xx drivers for the touch-panel, keyboard, lcd control
and power management into multiple files. This removes some dirty hacks
and improves the quality of the code.

- j720kbd.c - keyboard driver
* Converted to use the hpckbd(4) interface.
* Remove the old keymap file since it's no longer used.

- j720lcd.c - lcd brightness/control/power control

- j720pwr.c - power management
* Converted to use the hpcapm(4) interface.
* Fix the battery charge status. The values are non-linear so in order
to display a reasonable charge status we use a few charge points in
a table and interpolate between that.

- j720tp.c - touch-panel driver

- j720ssp.c - SSP port (on the SA-1110)

Many thanks to cube@ and uwe@ for providing useful feedback and reviewing
the changes.

Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
