iommu: Enable compile testing for some of drivers
Some of the IOMMU drivers can be compile tested to increase build coverage. The OMAP, Rockchip and Exynos drivers use device.dev_archdata.iommu field which does not exist on all platforms. The sPAPR TCE and ARM SMMU have also restrictions where they can be built. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Joerg Roedel <jroedel@suse.de>
