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).

This trims off the extra unusable memory from the lmb structure,
so we don't try to use it.

... instead of exporting it in arch/*/kernel/ppc_ksyms.c.

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.
