Also move the iommu_fwspec pointer from struct device into dev_iommu to have less iommu-related pointers in struct device. The bigger part of this patch-set moves the iommu_priv pointer from struct iommu_fwspec to dev_iommu, making is usable for iommu-drivers which do not use fwspecs. The changes for that were mostly straightforward, except for the arm-smmu (_not_ arm-smmu-v3) and the qcom iommu driver. Unfortunatly I don't have the hardware for those, so any testing of these drivers is greatly appreciated. Please review.
