Remove unnecessary include of <sys/malloc.h>.

- Use aprint*() more in xxx_attach().
- Add missing aprint_naive("\n").
- Remove extra spaces and tabs.
- KNF.

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

branches: 1.28.2; 1.28.12;
remove some bloat:
-cardbus doesn't use multiple interrupt lines like PCI, and it doesn't
use machanisms like interrupt line register and swizzling -- no need
to carry around dummy information, this is all dealt with by the
bridge
(I'm asking myself how "rbus_ppb" can work -- a bridge attached to
cardbus just can't work like a normal PCI bridge as far as interrupts
are concerned. I thing that should be a hardware specific driver
because behavior is not covered by a standard.)
-cardbus always uses 3.3V -- no need for a variable to keep track
of the voltage

This is *always* compiled with #define rbus 1, so get rid of the
conditional compilation.

Simplify interrupt (dis)establishment by two source transformations:

- cardbus_intr_disestablish(cc, cf, ih);
+ Cardbus_intr_disestablish(ct, ih);

- ih = cardbus_intr_establish(cc, cf, ...);
+ ih = Cardbus_intr_establish(ct, ...);

The identical change to a few other CardBus NICs has not caused any
problems, as expected, so I'm going to commit this rather safe change
and get on with the work.

Testers have been enlisted. I will revisit this change if I get any
negative responses.

branches: 1.26.2;
Use PCI_ constants and macros instead of CARDBUS_. Use
Cardbus_conf_{read,write}() instead of cardbus_conf_{read,write}().
Delete all of the CARDBUS_ constants and macros that replicate PCI_.

Compile-tested, only.

sc_csr is read & written from the PCI Command & Status Register,
so make its type pcireg_t.

Make fxp at cardbus detach during shutdown.

Stop calling (*cardbus_ctrl) to enable bus mastering, I/O and memory
spaces on the CardBus bridge. cbb(4) always enables that stuff,
anyway. In the process, avoid remembering what BAR we mapped by
writing CARDBUS_{IO,MEM}_ENABLE to sc_cben or sc_cbenable, and
record the BAR in use sc_bar, instead.

Replace more CARDBUS_ constants with PCI_ constants.

Compile-tested, only.

Start to tuck Cardbus under the PCI abstraction. Step #1, textual
substitution: for all practical purposes, pcitag_t and cardbustag_t
are interchangeable, so just use pcitag_t. Ditto pcireg_t and
cardbusreg_t.

While I'm here, don't make a copy (sc_intrline) of
cardbus_attach_args.ca_intrline unless we use it, later.

struct device * -> device_t, no functional changes intended.

struct cfdata * -> cfdata_t, no functional changes intended.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

branches: 1.19.4; 1.19.10;
clean up the cardbus interrupt stuff:
There were cardbus_intr_line_t and cardbus_intr_handle_t used intermixed
for the same variable, and that variable is pretty much useless because
cardbus doesn't follow the PCI interrupt swizzling etc scheme.
Useless interrupt numbers were printed on cardbus device attach.
So as a first step to sanity, kill cardbus_intr_handle_t and poison
cardbus_intr_line_t to discourage printing it as a %d.
Use cardbus_intr_line_t consistently throughout the code.
Remove the "interrupting at foo" messages because the information
is misleading. We could come up with a better interrupt vector
information, but because cardbus interrupts are mediated by pccbb
it would still be misleading.
