cxdtv(4): Use config_detach_children.

Merge thorpej-cfargs2.

branches: 1.19.8;
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: 1.18.10;
No need to use I2C_F_POLL here.

Cleanup i2c bus acquire / release, centralizing all of the logic into
iic_acquire_bus() / iic_release_bus(). "acquire" and "release" hooks
no longer need to be provided by back-end controller drivers (only if
they need special handling, e.g. powering on the i2c controller).
This results in the removal of a bunch of rendundant code from each
back-end controller driver.

Assert that we are not in hard interrupt context in iic_acquire_bus(),
iic_exec(), and iic_release_bus().

use pci_intr_establish_xname() everywhere

branches: 1.15.8; 1.15.10;
remove checks for failure after memory allocation calls that cannot fail:

kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

branches: 1.14.6;
make pci_intr_string and eisa_intr_string take a buffer and a length
instead of relying in local static storage.

remove unused variables.

branches: 1.12.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

branches: 1.11.6;
Use pci_aprint_devinfo(9) instead of pci_devinfo+aprint_{normal,naive}
where it looks straightforward, and pci_aprint_devinfo_fancy in a few
others where drivers want to supply their own device names instead
of the pcidevs generated one. More complicated cases, where names
are composed at runtime, are left alone for now. It certainly makes
sense to simplify the drivers here rather than inventing a catch-all API.
This should serve as as example for new drivers, and also ensure
consistent output in the AB_QUIET ("boot -q") case. Also, it avoids
excessive stack usage where drivers attach child devices because the
buffer for the device name is not kept on the local stack anymore.

Only match supported boards.

branches: 1.9.2; 1.9.6;
Define and use symbolic bits in registers.

have pci register itself as a module, and make PCI driver modules depend on it

modify the dtv device api so hardware drivers can be loaded independently
of the dtv module

Remove unconditional debugging code. Also, a few other cleanups.
