Andrew Turner	bc9b178cd0	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.

Ian Lepore	ecaecbc7d8	Make simplebus a base class of ofwbus. This allows the elimination of ... duplicated code in the two classes, and also allows devices in FDT-based systems to declare simplebus as their parent and still work correctly when the FDT data describes the device at the root of the tree rather than as a child of a simplebus (which is common for interrupt, clock, and power controllers).
