The IOMMU DT adaptation support uses the device name instead of an iommu object name. Fixup the ISP device archdata MMU name at runtime if using DT-boot. This allows the OMAP3 camera to be functional in both legacy and DT boots. The iommu object names should eventually vanish when all the IOMMU users have been converted to DT nodes.
