Use the IS_ENABLED() helper macro to ensure that the configfs group is initialized either when configfs is built-in or when configfs is built as a module. Otherwise software device creation will result in undefined behaviour when configfs is built as a module since the configfs group for the device not properly initialized. Similar to commit b2f0c09664b7 ("iio: sw-trigger: Fix config group initialization").
