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).

-# 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.
