Revert "iommu/of: Delete usage of driver_deferred_probe_check_state()"
This reverts commit b09796d528bbf06e3e10a4a8f78038719da7ebc6. An issue was reported[1] on the original commit. I'll need to address that before I can delete the use of driver_deferred_probe_check_state(). So, bring it back for now.
