[PATCH] powerpc: Move various ppc64 files with no ppc32 equivalent to powerpc

This patch moves a bunch of files from arch/ppc64 and
include/asm-ppc64 which have no equivalents in ppc32 code into
arch/powerpc and include/asm-powerpc.  The file affected are:
	abs_addr.h
	compat.h
	lppaca.h
	paca.h
	tce.h
	cpu_setup_power4.S
	ioctl32.c
	firmware.c
	pacaData.c

The only changes apart from the move and corresponding Makefile
changes are:
	- #ifndef/#define in includes updated to _ASM_POWERPC_ form
	- trailing whitespace removed
	- comments giving full paths removed
	- pacaData.c renamed paca.c to remove studlyCaps
	- Misplaced { moved in lppaca.h

Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64), built
for 32-bit powermac (ARCH=powerpc).
