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.

+	  This enables support for the Zorro bus in the Amiga. If you have

+	  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
+	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.
