soc: integrator: Use custom soc attribute group instead of device_create_file
Commit c31e73121f4c ("base: soc: Handle custom soc information sysfs entries") introduced custom soc attribute group in soc_device_attribute structure but there are no users treewide. 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.
