qcacmn: Use dma_iommu_mapping only if ENABLE_SMMU_S1_TRANSLATION defined

In standard linux kernel, dma_iommu_mapping is not defined for arm64, while
in qualcomm linux kernel, dma_iommu_mapping is defined for arm and arm64.
To fix build error in standard linux kernel, use struct dma_iommu_mapping
only when ENABLE_SMMU_S1_TRANSLATION is defined.
