[PATCH] enable multiboot2 loader on i386-ieee1275

[Robert Millan]

This makes multiboot2 work on i386-ieee1275.  Tested both with elf32 and
elf64 images.

In case of elf32 OFW images, they won't work because EAX is used for multiboot
information and can't hold the needed pointer to OFW callback interface.  See
the comment I added to the draft:
