Ian Lepore 2a74fe2c96 Fail to probe on simplebus nodes that lack a "ranges" property.
Increasingly, FDT data has the "simple-bus" compatible string on nodes
that have children, but we wouldn't consider them to be busses.  If the
node lacks a ranges property then we will fail to attach successfully,
so fail to probe as well.
