iommu/omap: Reset the domain field upon detaching
The .domain field in omap_iommu struct is set properly when the OMAP IOMMU device is attached to, but is never reset properly on detach. Reset this properly so that the OMAP IOMMU debugfs logic can depend on this field before allowing the debugfs operations.
