Add the nodes to describe the Adreno GPU and GMU devices for sdm845.

This has the following dependencies:

[v11,1/9] dt-bindings: opp: Introduce opp-level bindings
https://patchwork.kernel.org/patch/10755199/

And the following patches already in Rob's msm-next:
msm-next:d1c9cadea6f7 ("drm/msm/gpu: Remove hardcoded interrupt name")
msm-next:b08b92546807 ("drm/msm: drop interrupt-names")
msm-next:24937c540917 ("dt-bindings: drm/msm/a6xx: Document GMU and update GPU bindings")

And finally drm/msm: Fix A6XX support for opp-level
https://patchwork.freedesktop.org/patch/276756/

Which is not merged because it too depends on Rajendra's stack.
