With ARCH=powerpc we assume the presence of a device tree, so we don't
require any support for the old bi_recs method of passing boot
parameters. Likewise, we've never needed it for ppc64, but we still
had an include/asm-ppc64/bootinfo.h from which nothing was used. This
patch removes that file, and all references to it in arch/ppc64 and
arch/powerpc. A related, unused variable 'boot_mem_size' is also
removed from setup_32.c. The bootinfo stuff remains in ARCH=ppc for
the time being.
Built and booted on Power5 (ARCH=ppc64 and ARCH=powerpc), built for
32-bit powermac (ARCH=powerpc and ARCH=ppc).

SMP still needs more work but UP gets as far as starting userspace
at least. This uses the 64-bit-style code for spinning up the cpus.

This creates a new arch/powerpc/kernel/setup-common.c with various
bits that setup_32.c and setup_64.c had in common - functions like
machine_shutdown/restart/power_off, show_cpuinfo, set_preferred_console
etc.

* Removed of_show_percpuinfo and just report CPU frequency in generic
show_cpuinfo code.
* Killed OCP and PPC_SYS related code which doesn't belong in the
merge tree

This brings in a lot of changes from arch/ppc64/kernel/pmac_*.c to
arch/powerpc/platforms/powermac/*.c and makes various minor tweaks
elsewhere. On the powermac we now initialize ppc_md by copying
the whole pmac_md structure into it, which required some changes in
the ordering of initializations of individual fields of it.

I missed a few places where ppc code was still assuming that the
ppc_md.show_[per]cpuinfo functions returned int.

We were initializing the btext stuff from prom_init(), thus breaking
the rule that all communication between prom_init() and the rest of
the kernel has to be via the flattened device tree. This removes
the btext initialization calls from prom_init() and initializes it
instead after the device tree is unflattened. It would be nice to
do it earlier, but that needs some more infrastructure to find the
properties we need in the flattened device tree.

This doesn't change any code, just renames things so we consistently
have foo_32.c and foo_64.c where we have separate 32- and 64-bit
versions.
