Overhaul of the ISA autoconfiguration code to support direct

* Change the isa_attach_args to have arrays of io, mem, irq, drq
resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.

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?).

Fix silent hang during config_console() (before consinit()) on Milan.

config_console() was a dirty hack used by ancient m68k ports
to probe and initialize console devices before "real" configure(9),
using subset of configure(9) functions.

In that case, most device specific data (except I/O access method)
are not initialized so we must not access device specific device_t and
softc structures in config_console() cases.

fix atari builds in two ways:
- isa_detach_hook() was missing a parameter name (hi dyoung!)
- PCI_CONF_SIZE -> PCI_CONFIG_SIZE; pcivar.h has a PCI_CONF_SIZE now (hi jak!)

isa_detach_hook() needs two arguments, the first an isa_chipset_tag_t.

These are stragglers from my last commit ("Let us safely detach
the ISA bus and devices attaching to the ISA bus"). Define
isa_detach_hook() in MD ISA implementations. Define isa_dmadestroy().

Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Phase out the use of a string as first "attach args" member to control
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

Make things work with the new autoconf stuff:
- The pcibus is now called 'pcib' and the isabus 'isab'. Their attributes are

Otherwise we end up without a console.

Add isa_dma{freeze,thaw}(), used to temporarily stop and then restart
all ISA DMA. Needed by e.g. the SmartCard reader for Sharks.

Change the ISA DMA API to take an isa_chipset_tag_t rather than
a struct device * corresponding to the ISA bus device. The ISA DMA
controller driver functions have been renamed and now take a struct
isa_dma_state *, and are called indirectly by machine-dependent code
which provides the DMA state.

These changes allow e.g. `ofisa' (the OpenFirmware configuration
mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA
DMA controller code.
