	src/sys/arch/cobalt/pci: pcib.c

Log Message:
Cleanup ICU (i8259 compatible PIC) interrupt handling code:
- move ICU interrupt stuff from pci/pcib.h to cobalt/machdep.c
  because ICU should be initialized before pcib is attached
- initialize ICU more properly
- check interrupt types and set ELCR (edge/level control registers)
  accordingly in icu_intr_establish()
- check requested IRQ line and call only a necessary hander in icu_intr()
- use specific EOI to ack interrupts rather than AEOI
- use macro defined in <dev/ic/i8259reg.h>
