[PATCH v2 1/9] ARM: OMAP: iommu: fix including iommu.h without IOMMU_API selected

From: Omar Ramirez Luna
Date: Wed Sep 12 2012 - 15:46:00 EST

If included without IOMMU_API being selected it will break

In function 'dev_to_omap_iommu':
error: 'struct dev_archdata' has no member named 'iommu'

This will be seen when hwmod includes iommu.h to get the
structure for attributes. Also needed for tidspbridge
incremental migration to use iommu code.
