[0/6] Add a6xx GPU state capture

Message

This stack adds support for capturing the A6xx GPU state.

The A6xx GPU state is comprehensive including registers for
the GPU and the GMU, shader caches, context clusters and
debugbus state.

It isn't as straightforward to capture the state as with
previous targets. Some of the state is located behind
apertures and other registers have special access rules
so the complete state is defined by a hodgepodge of lists
and structs which makes the code appear way more complex
than it is.

Jordan Crouse (6):
  drm/msm/a6xx: rnndb updates for a6xx
  drm/msm/a6xx: Fix PDC register overlap
  drm/msm/a6xx: Rename gmu phandle to qcom,gmu
  drm/msm/gpu:  Move gpu_poll_timeout() to adreno_gpu.h
  drm/msm/adreno: Don't capture registers if target doesn't need them
  drm/msm/a6xx: Add a6xx gpu state
