We now use the merged time.c for both 32-bit and 64-bit compilation
with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32.
This removes setup_default_decr (folds its function into time_init)
and moves wakeup_decrementer into time.c.  This also makes an
asm-powerpc/rtc.h.

This is a bunch of mostly small fixes that are needed to get
ARCH=powerpc to compile for 64-bit.  This adds setup_64.c from
arch/ppc64/kernel/setup.c and locks.c from arch/ppc64/lib/locks.c.

Since lparmap.s gets included in arch/powerpc/kernel/head_64.S,
this avoids depending on a file in another directory.

Use idle_power4.S from ppc64 as we are not going to support
32 bit power4 in the merged tree.

Merge ppc64 traps.c into powerpc traps.c:
	use ppc64 versions of exception routine names
		(as they don't have StudlyCaps)
	make all the versions if die() have the same
		prototype

Misc steps to incorporate the flat device tree on iSeries.

- define iseries_probe()
- call build_iSeries_Memory_Map() earlier
- return __pa() of the flat device tree from iSeries_early_setup()
- actually call early_setup() for iSeries
- add iseries_md to machdep_calls
- build prom.o for iSeries
- enable /proc/device-tree for iSeries
