While trying to understand the motivation and tried to use it, it was found lot of existing custom attributes can moved to use it instead of device_create_file. Though most of these never remove/cleanup the custom attribute as they never call soc_device_unregister, using these custom attribute group eliminate the need for any cleanup as the driver infrastructure will take care of that. Let us remove device_create_file and start using the custom attribute group in soc_device_attribute.
