[POWERPC] Remove the dregs of APUS support from arch/powerpc

APUS (the Amiga Power-Up System) is not supported under arch/powerpc
and it's unlikely it ever will be.  Therefore, this patch removes the
fragments of APUS support code from arch/powerpc which have been
copied from arch/ppc.

A few APUS references are left in asm-powerpc in .h files which are
still used from arch/ppc.

bool "Amiga 1200/600 PCMCIA support"
depends on APUS && EXPERIMENTAL
help
Include support in the kernel for pcmcia on Amiga 1200 and Amiga
600. If you intend to use pcmcia cards say Y; otherwise say N.
config AMIGA_BUILTIN_SERIAL
tristate "Amiga builtin serial support"
depends on APUS
help
If you want to use your Amiga's built-in serial port in Linux,
answer Y.
To compile this driver as a module, choose M here.
config GVPIOEXT
tristate "GVP IO-Extender support"
depends on APUS
help
If you want to use a GVP IO-Extender serial card in Linux, say Y.
Otherwise, say N.
config GVPIOEXT_LP
tristate "GVP IO-Extender parallel printer support"
depends on GVPIOEXT
help
Say Y to enable driving a printer from the parallel port on your
GVP IO-Extender card, N otherwise.
config GVPIOEXT_PLIP
tristate "GVP IO-Extender PLIP support"
depends on GVPIOEXT
help
Say Y to enable doing IP over the parallel port on your GVP
IO-Extender card, N otherwise.
config MULTIFACE_III_TTY
tristate "Multiface Card III serial support"
depends on APUS
help
If you want to use a Multiface III card's serial port in Linux,
answer Y.
To compile this driver as a module, choose M here.
config A2232
tristate "Commodore A2232 serial support (EXPERIMENTAL)"
depends on EXPERIMENTAL && APUS
---help---
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"
will also be built as a module. This has to be loaded before
"ser_a2232". If you want to do this, answer M here.
config WHIPPET_SERIAL
tristate "Hisoft Whippet PCMCIA serial support"
depends on AMIGA_PCMCIA
help
HiSoft has a web page at <http://www.hisoft.co.uk/>, but there
is no listing for the Whippet in their Amiga section.
config APNE
tristate "PCMCIA NE2000 support"
depends on AMIGA_PCMCIA
help
If you have a PCMCIA NE2000 compatible adapter, say Y. Otherwise,
say N.
To compile this driver as a module, choose M here: the
module will be called apne.
config SERIAL_CONSOLE
bool "Support for serial port console"
depends on APUS && (AMIGA_BUILTIN_SERIAL=y || GVPIOEXT=y || MULTIFACE_III_TTY=y)
config HEARTBEAT
bool "Use power LED as a heartbeat"
depends on APUS
help
Use the power-on LED on your machine as a load meter. The exact
behavior is platform-dependent, but normally the flash frequency is
a hyperbolic function of the 5-minute load average.
