An impl driver might want to allocate its own type of vIOMMU object or the standard IOMMU_VIOMMU_TYPE_ARM_SMMUV3 by setting up its own SW/HW bits, as the tegra241-cmdqv driver will add IOMMU_VIOMMU_TYPE_TEGRA241_CMDQV.
Add vsmmu_size/type and vsmmu_init to struct arm_smmu_impl_ops. Prioritize them in arm_smmu_get_viommu_size() and arm_vsmmu_init().
