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

This patch moves a bunch more 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:
	hvcall.h
	proc_ppc64.c
	sysfs.c
	lparcfg.c
	rtas_pci.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

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