Sricharan R a37b19a384 iommu/of: Ignore all errors except EPROBE_DEFER ... While deferring the probe of IOMMU masters, xlate and add_device callbacks called from of_iommu_configure can pass back error values like -ENODEV, which means the IOMMU cannot be connected with that master for real reasons. Before the IOMMU probe deferral, all such errors were ignored. Now all those errors are propagated back, killing the master's probe for such errors. Instead ignore all the errors except EPROBE_DEFER, which is the only one of concern and let the master work without IOMMU, thus restoring the old behavior. Also make explicit that of_dma_configure handles only -EPROBE_DEFER from of_iommu_configure.
