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".
Fixes: b17336c55d89 ("iommu/mediatek: add support for mtk iommu generation one HW")
