powerpc: Merge enough to start building in arch/powerpc.

This creates the directory structure under arch/powerpc and a bunch
of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.

For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
to files in those directories and files outside arch/powerpc.

The boot directory is still not merged.  That's going to be interesting.

+config AMIGA

+          This enables support for the Zorro bus in the Amiga. If you have
+          expansion cards in your Amiga that conform to the Amiga
+          AutoConfig(tm) specification, say Y, otherwise N. Note that even
+          expansion cards that do not fit in the Zorro slots but fit in e.g.
+          the CPU slot may fall in this category, so you have to say Y to let
+          Linux use these.

+config A2232

+        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.
