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").
Fixes: 0f3a8c3f34f7 ("iio: Add support for creating IIO devices via configfs")
