Log: Allow child classes of simplebus to call attach directly Reduce code duplication when a bus is subclassed from simplebus by allowing them to call simplebus_attach directly. This is useful when the child bus will just implement the same calls. As not all children will expect to have a ranges property, e.g. the Raspberry Pi firmware, allow this property to be missing.
