drm/etnaviv: initialize iommu domain page size
Since d16e0faab91 (iommu: Allow selecting page sizes per domain) the iommu core demands the page size to be set per domain, otherwise any mapping attempts will be dropped. Make sure to set a valid page size for the etnaviv iommu. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
