There exist two Mediatek iommu drivers for the two different generations of the device. But both drivers have the same name "mtk-iommu". This breaks the registration of the second driver: Error: Driver 'mtk-iommu' is already registered, aborting... Fix this by changing the name for first generation to "mtk-iommu-v1".
