of: make kobject and bin_attribute support configurable
Having device_nodes be kobjects is only needed if sysfs or OF_DYNAMIC is enabled. Otherwise, having a kobject in struct device_node is unnecessary bloat in minimal kernel configurations. Likewise, bin_attribute is only needed in struct property when sysfs is enabled, so we can make it configurable too.
