The TC device addresses are defined in KSEG1, but this confuses
bus_space(9) which expects bus addresses and not kernel virtual
addresses. Pull the addresses back to bus addresses with
MIPS_KSEG1_TO_PHYS().

XXX: Fix this properly one day (without storing KSEG1 addrs in
the TC device configuration).

Fixes problem with TURBOchannel pmaxes panicing during
autoconfiguartion.

ANSIfy functions with function-pointer arguments

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!

Mostly they have function pointer parameters.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */

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.)

Redo interrupt establishment, based in part on work on the
[nisimura-pmax-wscons] branch and suggestions from Toru Nisimura:
- Remove bogus tc_slot_info[] name for interrupt handling array
and replace with simplified struct intrhand intrtab[] array.
- Add intr_establish() and intr_disestablish() function pointers
to struct platform and initialise this in each model-specific
initialisation, and remove global tc_enable_interrupt function
pointer.
- Remove model-specific function declarations from ibus/ibusvar.h.
This is functionally identical to the current scheme, and doesn't
yet try to commonise interrupt establishment by bus type as the
[nisimura-pmax-wscons] branch does.

Also, move cpuspeed variable from autoconf.c to machdep.c
