Fix detection of "real mode" when /options/real-mode? doesn't exist.

        * include/grub/ieee1275/ieee1275.h (grub_ieee1275_mmu): New variable
        declaration.
        * kern/powerpc/ieee1275/cmain.c (grub_ieee1275_mmu): New variable.
        (grub_ieee1275_find_options): If `grub_ieee1275_mmu' is 0, set
        `GRUB_IEEE1275_FLAG_REAL_MODE'.
        (cmain): Intialize `grub_ieee1275_mmu' (using /chosen/mmu integer
        property).
        * kern/powerpc/ieee1275/openfw.c (grub_map): Rely on pre-initialized
        `grub_ieee1275_mmu' rather than obtaining a handler on every call.
