------------------ [ Upstream commit 89cddc563743cb1e0068867ac97013b2a5bf86aa ] qcom,smmu-v2 is an arm,smmu-v2 implementation with specific clock and power requirements. On msm8996, multiple cores, viz. mdss, video, etc. use this smmu. On sdm845, this smmu is used with gpu. Add bindings for the same.
