powerpc: Move ppc64 boot wrapper code over to arch/powerpc
This also extends the code to handle 32-bit ELF vmlinux files as well as 64-bit ones. This is sufficient for booting on new-world 32-bit powermacs (i.e. all recent machines). Signed-off-by: Paul Mackerras <paulus@samba.org>

-# Makefile for making ELF bootable images for booting on CHRP
-# using Open Firmware.
-#
-# Geert Uytterhoeven September 1997
-#
-# Based on coffboot by Paul Mackerras
-# Simplified for ppc64 by Todd Inglett
-#
-# NOTE: this code is built for 32 bit in ELF32 format even though
-# it packages a 64 bit kernel. We do this to simplify the
-# bootloader and increase compatibility with OpenFirmware.
-#
-# To this end we need to define BOOTCC, etc, as the tools
-# needed to build the 32 bit image. These are normally HOSTCC,
-# but may be a third compiler if, for example, you are cross
-# compiling from an intel box. Once the 64bit ppc gcc is
-# stable it will probably simply be a compiler switch to
-# compile for 32bit mode.
-# To make it easier to setup a cross compiler,
-# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
-# in the toplevel makefile.
