[PATCH v2 4/4] Revert "iommu/of: Delete usage of driver_deferred_probe_check_state()"

[Saravana Kannan]

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.
