[POWERPC] Remove APUS support from arch/ppc
Current status of APUS: - arch/powerpc/: removed in 2.6.23 - arch/ppc/: marked BROKEN since 2 years This therefore removes the remaining parts of APUS support from arch/ppc, include/asm-ppc, arch/powerpc and include/asm-powerpc.

- * 11/07/96: rewritten interrupt handling, irq lists are exists now only for
- * this sources where it makes sense (VERTB/PORTS/EXTER) and you must
- * be careful that dev_id for this sources is unique since this the
- * only possibility to distinguish between different handlers for
- * free_irq. irq lists also have different irq flags:
- * - IRQ_FLG_FAST: handler is inserted at top of list (after other
- * fast handlers)
- * - IRQ_FLG_SLOW: handler is inserted at bottom of list and before
- * they're executed irq level is set to the previous
- * one, but handlers don't need to be reentrant, if
- * reentrance occurred, slow handlers will be just
- * called again.
- * The whole interrupt handling for CIAs is moved to cia.c
- * /Roman Zippel
- *
- * 07/08/99: rewamp of the interrupt handling - we now have two types of
- * interrupts, normal and fast handlers, fast handlers being
- * marked with SA_INTERRUPT and runs with all other interrupts
- * disabled. Normal interrupts disable their own source but
- * run with all other interrupt sources enabled.
- * PORTS and EXTER interrupts are always shared even if the
- * drivers do not explicitly mark this when calling
- * request_irq which they really should do.
- * This is similar to the way interrupts are handled on all
- * other architectures and makes a ton of sense besides
- * having the advantage of making it easier to share
- * drivers.
