PPC32: remove support for IBM iSeries machines.

All the iSeries machines that can run Linux are 64-bit PowerPC
machines and are now supported by the ppc64 kernel.  Since no-one
is interested in maintaining the iSeries support in the ppc32
kernel, I am removing it.

---help---
If you have a CD-ROM drive that is neither SCSI nor IDE/ATAPI, say Y
here, otherwise N. Read the CD-ROM-HOWTO, available from
<http://www.linuxdoc.org/docs.html#howto>.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about these CD-ROM drives. If you are unsure what you
have, say Y and find out whether you have one of the following
drives.
For each of these drivers, a file Documentation/cdrom/{driver_name}
exists. Especially in cases where you do not know exactly which kind
of drive you have you should read there. Most of these drivers use a
file drivers/cdrom/{driver_name}.h where you can define your
interface parameters and switch some internal goodies.
All these CD-ROM drivers are also usable as a module ( = code which
can be inserted in and removed from the running kernel whenever you
want). If you want to compile them as module, say M instead of Y and
read <file:Documentation/modules.txt>.
If you want to use any of these CD-ROM drivers, you also have to
answer Y or M to "ISO 9660 CD-ROM file system support" below (this
answer will get "defaulted" for you if you enable any of the Linux
CD-ROM drivers).
