From: Matthias Brugger <matthias.bgg@gmail.com>
[ Upstream commit 395df08d2e1de238a9c8c33fdcd0e2160efd63a9 ]
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".
