Modified Files:
	src/sys/arch/sgimips/sgimips: bus.c clock.c console.c cpu.c machdep.c
Added Files:
	src/sys/arch/sgimips/sgimips: int.c
Removed Files:
	src/sys/arch/sgimips/sgimips: ip2x.c ip32.c

Log Message:
Large rototill of the lowlevel code:

* move all device-specific bitbanging to the device drivers in question --
  i.e., the ip32 init code doesn't access the CRIME registers directly but
  instead trusts the CRIME driver to DTRT.  machdep.c is cleaner thereby.
* introduce int.c, which handles the interrupt-controller goo formerly
  in ip2x.c.
* unify the CPU interrupt handler, with CRIME, INT2, and the various timer
  handlers hooked in via pointers in the platform struct.
* eliminate ip2x.c and ip32.c.  After the interrupt handler cleanup, the
  actual platform-dependent code was so minimal (rev identification, mask level
  initialization) that it made sense to move it into machdep.c
* "#ifdef DEBUG printf("foo"); #endif" becomes aprint_debug.

Tested on my ip22 and ip32.  Discussed with pooka@, rafal@.
