[patch] small PPC cleanups

[Hollis Blanchard]

This patch corrects a couple of small issues I've come across in the PPC
code:
- struct module_info is unused
- we're declaring space for a stack but not using it
- GRUB_IEEE1275_MODULE_BASE is a 7-char address; add the missing 0

I've tested the stack change on briQ and G3. If there are no comments I
will commit this patch in a couple days.

        * boot/powerpc/ieee1275/cmain.c (module_info): Remove struct.
        * boot/powerpc/ieee1275/crt0.S (_start): Use init_stack.
        * include/grub/powerpc/ieee1275/kernel.h (GRUB_IEEE1275_MODULE_BASE):
        Correct cosmetic typo.
