iommu/arm-smmu: Refactor qcom_smmu structure to include single pointer
qcom_smmu_match_data is static and constant so refactor qcom_smmu to
store single pointer to qcom_smmu_match_data instead of replicating
multiple child members of the same and handle the further dereferences
in the places that want them.
