Pull up following revision(s) (requested by tsutsui in ticket #893):
        sys/arch/macppc/stand/ofwboot/Locore.c: revision 1.26
Don't set garbages into BAT registers, which was broken in rev 1.25.
Should fix PR port-macppc/50018 (though there is no response for 3 weeks),
and should be pulled up to netbsd-7.
