Move special handling of qcom,adreno-smmu into qcom_smmu_create()
function. This allows us to further customize the Adreno SMMU
implementation.

Note, this also adds two entries to the qcom_smmu_impl_of_match table.
They were used with the qcom,adreno-smmu compat and were handled by the
removed clause.
