With ARCH=powerpc, CONFIG_PPC_OF should always be set. It's supposed to
be set when the device-tree accessors exist which they always do.

Besides, I'll be removing support for !MULTIPLATFORM too :) (Except for
iSeries at least for a little while). Look at the patch I posted that
removes _machine for an idea of where things are going.

Why do you want CONFIG_PPC_OF not set ?
