We could make CONFIG_OF depend on CONFIG_HAVE_OF_SUPPORT and let OF
select OF_EARLY_FLATTREE if ARCH_WANT_EARLY_FLATTREE for instance. So
that part would work in a generic way.

For OF-only platforms you would have to go to drivers/of
before you can enable the specific SoC/board. So it could lead to
something like "first enable scsi disk before you can enable usb
storage".

I like it :) For now I rename to USE_OF.
