Subject: iio: sw-trigger: Fix config group initialization

From: Lars-Peter Clausen <[email protected]>

commit b2f0c09664b72b2f8c581383a9337ac3092e42c8 upstream.

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 trigger creation will result in undefined behaviour when configfs is built as a mdoule since the configfs group for the trigger is not properly initialized.

Fixes b662f809d410 ("iio: core: Introduce IIO software triggers")
