Add some tests of driver model functionality. Coverage includes: - basic init - binding of drivers to devices using platform_data - automatic probing of devices when referenced - availability of platform data to devices - lifecycle from bind to probe to remove to unbind - renumbering within a uclass when devices are probed/removed - calling driver-defined operations - deactivation of drivers when removed - memory leak across creation and destruction of drivers/uclasses - uclass init/destroy methods - automatic probe/remove of children/parents when needed This function is enabled for sandbox, using CONFIG_DM_TEST.
