iommu/omap: fix device leaks on probe_device()

Browse source

commit b587069106 upstream.

Make sure to drop the references taken to the iommu platform devices
when looking up their driver data during probe_device().

Note that the arch data device pointer added by commit 604629bcb5
("iommu/omap: add support for late attachment of iommu devices") has
never been used. Remove it to underline that the references are not
needed.

Fixes: 9d5018deec ("iommu/omap: Add support to program multiple iommus")
Fixes: 7d6827748d ("iommu/omap: Fix iommu archdata name for DT-based devices")
