Add DT nodes for the sdm845 GPU/GMU (graphics management unit) and the companion
arm-smmu-v2 compatible SMMU.

This builds on the following dependencies -
https://patchwork.kernel.org/patch/10286369/ - bindings for qcom,level
https://patchwork.kernel.org/patch/10281599/ - qcom,smmu-v2 bindings

And requires these two changes for the driver:

https://patchwork.freedesktop.org/patch/243512/ - use new PDC sections
https://patchwork.freedesktop.org/patch/243513/ - use qcom,gmu instead of gmu

I think we are still waiting for the dependencies to merge but this should
at least be usable for anybody with a target that wants to get the GPU up
and happy.

[v3 - Split GMU PDC region into two GPU specific sections, fix indentation,
  really use qcom,gmu for the phandle name]
[v2 - changed qcom,arc-level to qcom,level following discussion with Viresh;
change gmu phandle to qcom,gmu per Rob]
