[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.

This option supports the 2232 7-port serial card shipped with the
Amiga 2000 and other Zorro-bus machines, dating from 1989. At
a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
ports were connected with 8 pin DIN connectors on the card bracket,
for which 8 pin to DB25 adapters were supplied. The card also had
jumpers internally to toggle various pinning configurations.
This driver can be built as a module; but then "generic_serial"

*
* 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.

*
* Basically what is needed to replace functionality found in
* arch/m68k allowing Amiga drivers to work under APUS.
* Bits of code and/or ideas from arch/m68k and arch/ppc files.
*
* TODO:
* This file needs a *really* good cleanup. Restructure and optimize.
* Make sure it can be compiled for non-APUS configs. Begin to move
* Amiga specific stuff into mach/amiga.
