Hmm, yes.  I don't really know what to do here, so I left it for now.
ARM64 does indeed select OF, but I'm not sure whether that's an actual
arch dependency or just a convenience because most ARM64 platforms
rely on it.  I know there are some that use ACPI, and I don't know
whether they *also* need OF.
